Labour Party (UK)
The Labour Party is a centre-left political party in the United Kingdom that has been described as an alliance of social democrats, democratic socialists and trade unionists. In all general elections since 1922, Labour has been either the governing party or the Official Opposition. There have been six Labour prime ministers and thirteen Labour ministries.

The Labour Party was founded in 1900, having grown out of the trade union movement and socialist parties of the 19th century. It overtook the Liberal Party to become the main opposition to the Conservative Party in the early 1920s, forming two minority governments under Ramsay MacDonald in the 1920s and early 1930s. Labour served in the wartime coalition of 1940–1945, after which Clement Attlee's Labour government established the National Health Service and expanded the welfare state from 1945 to 1951. Under Harold Wilson and James Callaghan, Labour again governed from 1964 to 1970 and 1974 to 1979. In the 1990s, Tony Blair took Labour to the centre as part of his New Labour project which governed under Blair and then Gordon Brown from 1997 to 2010.

The Labour Party currently forms the Official Opposition in the Parliament of the United Kingdom, having won the second-largest number of seats in the 2019 general election. The leader of the party and leader of the opposition is Keir Starmer. Labour is the largest party in the Welsh Parliament, being the main party in the current Welsh government. The party is the third-largest in the Scottish Parliament. Labour is a member of the Party of European Socialists and Progressive Alliance, and holds observer status in the Socialist International. The party includes semi-autonomous Scottish and Welsh branches, and supports the Social Democratic and Labour Party (SDLP) in Northern Ireland, although it still organises there. As of November 2020, Labour has nearly 500,000 registered members, one of the largest memberships of any party in Europe.

 History 

 Origins and the Independent Labour Party (1860–1900) 
thumb|left|upright|The original Liberty logo, in use until 1983
The Labour Party originated in the late 19th century, meeting the demand for a new political party to represent the interests and needs of the urban working class, a demographic which had increased in number, and many of whom only gained suffrage with the passage of the Representation of the People Act 1884. Some members of the trades union movement became interested in moving into the political field, and after further extensions of the voting franchise in 1867 and 1885, the Liberal Party endorsed some trade-union sponsored candidates. The first Lib–Lab candidate to stand was George Odger in the Southwark by-election of 1870. In addition, several small socialist groups had formed around this time, with the intention of linking the movement to political policies. Among these were the Independent Labour Party (ILP), the intellectual and largely middle-class Fabian Society, the Marxist Social Democratic FederationMartin Crick, The History of the Social-Democratic Federation and the Scottish Labour Party.

At the 1895 general election, the ILP put up 28 candidates but won only 44,325 votes. Keir Hardie, the leader of the party, believed that to obtain success in parliamentary elections, it would be necessary to join with other left-wing groups. Hardie's roots as a lay preacher contributed to an ethos in the party which led to the comment by 1950s General Secretary Morgan Phillips that "Socialism in Britain owed more to Methodism than Marx".Worley, Matthew (2009). The Foundations of the British Labour Party. p. 131. .

 Labour Representation Committee (1900–1906) 

thumb|upright|Keir Hardie, one of the Labour Party's founders and its first leader
In 1899, a Doncaster member of the Amalgamated Society of Railway Servants, Thomas R. Steels, proposed in his union branch that the Trade Union Congress call a special conference to bring together all left-wing organisations and form them into a single body that would sponsor Parliamentary candidates. The motion was passed at all stages by the TUC, and the proposed conference was held at the Congregational Memorial Hall on Farringdon Street, London on 26 and 27 February 1900. The meeting was attended by a broad spectrum of working-class and left-wing organisations—trades unions represented about one-third of the membership of the TUC delegates.‘The formation of the Labour Party – Lessons for today’  Jim Mortimer, 2000; Jim Mortimer was a General Secretary of the Labour Party in the 1980s

After a debate, the 129 delegates passed Hardie's motion to establish "a distinct Labour group in Parliament, who shall have their own whips, and agree upon their policy, which must embrace a readiness to cooperate with any party which for the time being may be engaged in promoting legislation in the direct interests of labour." This created an association called the Labour Representation Committee (LRC), meant to co-ordinate attempts to support MPs sponsored by trade unions and represent the working-class population. It had no single leader, and in the absence of one, the Independent Labour Party nominee Ramsay MacDonald was elected as Secretary. He had the difficult task of keeping the various strands of opinions in the LRC united. The 1900 general election, also referred to as the "Khaki election", came too soon for the new party to campaign effectively and total expenses for the election only came to £33. Only 15 candidatures were sponsored, but two were successful: Keir Hardie in Merthyr Tydfil and Richard Bell in Derby.

Support for the LRC was boosted by the 1901 Taff Vale Case, a dispute between strikers and a railway company that ended with the union being ordered to pay £23,000 damages for a strike. The judgement effectively made strikes illegal, since employers could recoup the cost of lost business from the unions. The apparent acquiescence of the Conservative Government of Arthur Balfour to industrial and business interests (traditionally the allies of the Liberal Party in opposition to the Conservatives' landed interests) intensified support for the LRC against a government that appeared to have little concern for the industrial proletariat and its problems.

In the 1906 general election, the LRC won 29 seats—helped by a secret 1903 pact between Ramsay MacDonald and Liberal Chief Whip Herbert Gladstone that aimed to avoid splitting the opposition vote between Labour and Liberal candidates in the interest of removing the Conservatives from office.

In their first meeting after the election the group's Members of Parliament decided to adopt the name "The Labour Party" formally (15 February 1906). Keir Hardie, who had taken a leading role in getting the party established, was elected as Chairman of the Parliamentary Labour Party (in effect, the leader), although only by one vote over David Shackleton after several ballots. In the party's early years the Independent Labour Party (ILP) provided much of its activist base as the party did not have individual membership until 1918 but operated as a conglomerate of affiliated bodies. The Fabian Society provided much of the intellectual stimulus for the party. One of the first acts of the new Liberal Government was to reverse the Taff Vale judgement.

The People's History Museum in Manchester holds the minutes of the first Labour Party meeting in 1906 and has them on display in the Main Galleries. Also within the museum is the Labour History Archive and Study Centre, which holds the collection of the Labour Party, with material ranging from 1900 to the present day.

 Early years (1906–1923) 
The December 1910 general election saw 42 Labour MPs elected to the House of Commons, a significant victory since, a year before the election, the House of Lords had passed the Osborne judgment ruling that trade union members would have to 'opt in' to sending contributions to Labour, rather than their consent being presumed. The governing Liberals were unwilling to repeal this judicial decision with primary legislation. The height of Liberal compromise was to introduce a wage for Members of Parliament to remove the need to involve the trade unions. By 1913, faced with the opposition of the largest trade unions, the Liberal government passed the Trade Disputes Act to allow unions to fund Labour MPs once more without seeking the express consent of their members.

During the First World War, the Labour Party split between supporters and opponents of the conflict but opposition to the war grew within the party as time went on. Ramsay MacDonald, a notable anti-war campaigner, resigned as leader of the Parliamentary Labour Party and Arthur Henderson became the main figure of authority within the party. He was soon accepted into Prime Minister H. H. Asquith's war cabinet, becoming the first Labour Party member to serve in government. Despite mainstream Labour Party's support for the coalition the Independent Labour Party was instrumental in opposing conscription through organisations such as the Non-Conscription Fellowship while a Labour Party affiliate, the British Socialist Party, organised a number of unofficial strikes.John Foster,  "Strike action and working-class politics on Clydeside 1914–1919." International Review of Social History 35#1 (1990): 33–70. Arthur Henderson resigned from the Cabinet in 1917 amid calls for party unity to be replaced by George Barnes. The growth in Labour's local activist base and organisation was reflected in the elections following the war, the co-operative movement now providing its own resources to the Co-operative Party after the armistice. The Co-operative Party later reached an electoral agreement with the Labour Party.

At the end of the First World War, the Government was attempting to provide support for the newly re-established Poland against Soviet Russia. Henderson sent telegrams to all local Labour Party organisations to ask them to organise demonstrations against supporting Poland, later forming the Council of Action, to further organise strikes and protests. Due to the number of demonstrations and the potential industrial impact across the country, Churchill and the Government was forced to end support for the Polish war effort.Jackson, Pete (13 October 2017). "The Russian Revolution and the British working class" . International Socialist (156). Retrieved 1 June 2020.

Henderson turned his attention to building a strong constituency-based support network for the Labour Party. Previously, it had little national organisation, based largely on branches of unions and socialist societies. Working with Ramsay MacDonald and Sidney Webb, Henderson in 1918 established a national network of constituency organisations. They operated separately from trade unions and the National Executive Committee and were open to everyone sympathetic to the party's policies. Secondly, Henderson secured the adoption of a comprehensive statement of party policies, as drafted by Sidney Webb. Entitled "Labour and the New Social Order", it remained the basic Labour platform until 1950. It proclaimed a socialist party whose principles included a guaranteed minimum standard of living for everyone, nationalisation of industry, and heavy taxation of large incomes and of wealth.Bentley B. Gilbert, Britain since 1918 (1980) p 49. It was in 1918 that Clause IV, as drafted by Sidney Webb, was adopted into Labour's constitution, committing the party to work towards "the common ownership of the means of production, distribution and exchange". With the Representation of the People Act 1918, almost all adult men (excepting only peers, criminals and lunatics) and most women over the age of thirty were given the right to vote, almost tripling the British electorate at a stroke, from 7.7 million in 1912 to 21.4 million in 1918. This set the scene for a surge in Labour representation in parliament.Rosemary Rees, Britain, 1890–1939 (2003), p. 200  The Communist Party of Great Britain was refused affiliation to the Labour Party between 1921 and 1923.

Meanwhile, the Liberal Party declined rapidly, and the party also suffered a catastrophic split which allowed the Labour Party to gain much of the Liberals' support.Trevor Wilson, The downfall of the Liberal Party, 1914–1935 (1966) ch 14  With the Liberals thus in disarray, Labour won 142 seats in 1922, making it the second-largest political group in the House of Commons and the official opposition to the Conservative government. After the election Ramsay MacDonald was voted the first official leader of the Labour Party.

 First Labour government and period in opposition (1923–1929) 

thumb|upright|Ramsay MacDonald, first Labour Prime Minister (1924 and 1929–1931)
The 1923 general election was fought on the Conservatives' protectionist proposals, but although they got the most votes and remained the largest party, they lost their majority in parliament, necessitating the formation of a government supporting free trade. Thus, with the acquiescence of Asquith's Liberals, Ramsay MacDonald became the first ever Labour Prime Minister in January 1924, forming the first Labour government, despite Labour only having 191 MPs (less than a third of the House of Commons). The most significant achievement of the first Labour government was the Wheatley Housing Act, which began a building programme of 500,000 municipal houses for rental to low paid workers. Legislation on education, unemployment, social insurance and tenant protection was also passed. However, because the government had to rely on the support of the Liberals it was unable to implement many of its more contentious policies such as nationalisation of the coal industry, or a capital levy. Although no radical changes were introduced, Labour demonstrating that they were capable of governing.

While there were no major labour strikes during his term, MacDonald acted swiftly to end those that did erupt. When the Labour Party executive criticised the government, he replied that, "public doles, Poplarism [local defiance of the national government], strikes for increased wages, limitation of output, not only are not Socialism, but may mislead the spirit and policy of the Socialist movement."

The government collapsed after only ten months when the Liberals voted for a Select Committee inquiry into the Campbell Case, a vote which MacDonald had declared to be a vote of confidence. The ensuing 1924 general election saw the publication, four days before polling day, of the forged Zinoviev letter, in which Moscow talked about a Communist revolution in Britain. The letter had little impact on the Labour vote—which held up. It was the collapse of the Liberal party that led to the Conservative landslide. The Conservatives were returned to power although Labour increased its vote from 30.7% to a third of the popular vote, most Conservative gains being at the expense of the Liberals. However, many Labourites blamed for years their defeat on foul play (the Zinoviev letter), thereby according to A. J. P. Taylor misunderstanding the political forces at work and delaying needed reforms in the party.

In opposition, MacDonald continued his policy of presenting the Labour Party as a moderate force. During the General Strike of 1926 the party opposed the general strike, arguing that the best way to achieve social reforms was through the ballot box. The leaders were also fearful of Communist influence orchestrated from Moscow. The party had a distinctive and suspicious foreign policy based on pacifism. Its leaders believed that peace was impossible because of capitalism, secret diplomacy, and the trade in armaments. That is it stressed material factors that ignored the psychological memories of the Great War, and the highly emotional tensions regarding nationalism and the boundaries of the countries.Kenneth E. Miller, Socialism and Foreign Policy: Theory and Practice in Britain to 1931 (1967) ch 4–7.

 Second Labour government (1929–1931) 

In the 1929 general election, the Labour Party became the largest in the House of Commons for the first time, with 287 seats and 37.1% of the popular vote. However MacDonald was still reliant on Liberal support to form a minority government. MacDonald went on to appoint Britain's first woman cabinet minister; Margaret Bondfield, who was appointed Minister of Labour.John Shepherd, The Second Labour Government: A reappraisal (2012). MacDonald's second government was in a stronger parliamentary position than his first, and in 1930 Labour was able to pass legislation to raise unemployment pay, improve wages and conditions in the coal industry (i.e. the issues behind the General Strike) and pass a housing act which focused on slum clearances.Morgan, Kevin. (2006) MacDonald (20 British Prime Ministers of the 20th Century), Haus Publishing, 

The government soon found itself engulfed in crisis as the Wall Street Crash of 1929 and eventual Great Depression occurred soon after the government came to power, and the slump in global trade hit Britain hard. By the end of 1930 unemployment had doubled to over two and a half million.Davies, A.J. (1996) To Build A New Jerusalem: The British Labour Party from Keir Hardie to Tony Blair, Abacus The government had no effective answers to the deteriorating financial situation, and by 1931 there was much fear that the budget was unbalanced, which was born out by the independent May Report which triggered a confidence crisis and a run on the pound. The cabinet deadlocked over its response, with several influential members unwilling to support the budget cuts (in particular a cut in the rate of unemployment benefit) which were pressed by the civil service and opposition parties. Chancellor of the Exchequer Philip Snowden refused to consider deficit spending or tariffs as alternative solutions. When a final vote was taken, the Cabinet was split 11–9 with a minority, including many political heavyweights such as Arthur Henderson and George Lansbury, threatening to resign rather than agree to the cuts. The unworkable split, on 24 August 1931, made the government resign. MacDonald was encouraged by King George V to form an all-party National Government to deal with the immediate crisis.Neil Riddell, Labour in Crisis: The Second Labour Government 1929–1931 (Manchester UP, 1999).Chris Wrigley, "The Fall of the Second MacDonald Government, 1931." in T.  Heppell and K. Theakston,  How Labour Governments Fall (Palgrave Macmillan UK, 2013) pp. 38–60.

The financial crisis grew worse, and decisive government action was needed, as the leaders of both the Conservative Party and the Liberal Party met with King George V and MacDonald, at first to discuss support for the spending cuts but later to discuss the shape of the next government. The king played the central role in demanding a National government be formed. On 24 August, MacDonald agreed to form a National Government composed of men from all parties with the specific aim of balancing the Budget and restoring confidence. The new cabinet had four Labourites (who formed a National Labour group) who stood with MacDonald, plus four Conservatives (led by Baldwin, Chamberlain) and two Liberals. MacDonald's moves aroused great anger among a large majority of Labour Party activists who felt betrayed. Labour unions were strongly opposed and the Labour Party officially repudiated the new National government. It expelled MacDonald and his supporters and made Henderson the leader of the main Labour party. Henderson led it into the general election on 27 October against the three-party National coalition. It was a disaster for Labour, which was reduced to a small minority of 52 seats. The Conservative-dominated National Government, led by MacDonald, won the largest landslide in British political history.

In 1931, Labour campaigned on opposition to public spending cuts, but found it difficult to defend the record of the party's former government and the fact that most of the cuts had been agreed before it fell. Historian Andrew Thorpe argues that Labour lost credibility by 1931 as unemployment soared, especially in coal, textiles, shipbuilding,  and steel. The working class increasingly lost confidence in the ability of Labour to solve the most pressing problem. The 2.5 million Irish Catholics in England and Scotland were a major factor in the Labour base in many industrial areas. The Catholic Church had previously tolerated the Labour Party, and denied that it represented true socialism. However, the bishops by 1930 had grown increasingly alarmed at Labour's policies toward Communist Russia, toward birth control and especially toward funding Catholic schools. They warned its members. The Catholic shift against Labour and in favour of the National government played a major role in Labour's losses.

 Labour in opposition (1931–1940) 
Arthur Henderson, elected in 1931 to succeed MacDonald, lost his seat in the 1931 general election. The only former Labour cabinet member who had retained his seat, the pacifist George Lansbury, accordingly became party leader.

The party experienced another split in 1932 when the Independent Labour Party, which for some years had been increasingly at odds with the Labour leadership, opted to disaffiliate from the Labour Party and embarked on a long, drawn-out decline.

Lansbury resigned as leader in 1935 after public disagreements over foreign policy. He was promptly replaced as leader by his deputy, Clement Attlee, who would lead the party for two decades. The party experienced a revival in the 1935 general election, winning 154 seats and 38% of the popular vote, the highest that Labour had achieved.John Bew,  Clement Attlee: The Man Who Made Modern Britain (2017).

As the threat from Nazi Germany increased, in the late 1930s the Labour Party gradually abandoned its pacifist stance and came to support re-armament, largely due to the efforts of Ernest Bevin and Hugh Dalton who by 1937 had also persuaded the party to oppose Neville Chamberlain's policy of appeasement.

 Wartime coalition (1940–1945) 

The party returned to government in 1940 as part of the wartime coalition. When Neville Chamberlain resigned in the spring of 1940, incoming Prime Minister Winston Churchill decided to bring the other main parties into a coalition similar to that of the First World War. Clement Attlee was appointed Lord Privy Seal and a member of the war cabinet, eventually becoming the United Kingdom's first Deputy Prime Minister.

A number of other senior Labour figures also took up senior positions: the trade union leader Ernest Bevin, as Minister of Labour, directed Britain's wartime economy and allocation of manpower, the veteran Labour statesman Herbert Morrison became Home Secretary, Hugh Dalton was Minister of Economic Warfare and later President of the Board of Trade, while A. V. Alexander resumed the role he had held in the previous Labour Government as First Lord of the Admiralty.

 Attlee government (1945–1951) 

thumb|left|upright|Clement Attlee, Prime Minister (1945–1951)
At the end of the war in Europe, in May 1945, Labour resolved not to repeat the Liberals' error of 1918, promptly withdrawing from government, on trade union insistence, to contest the 1945 general election in opposition to Churchill's Conservatives. Surprising many observers, Labour won a landslide victory, winning just under 50% of the vote with a majority of 159 seats.

Although Clement Attlee was no great radical himself, Attlee's government proved one of the most radical British governments of the 20th century, enacting Keynesian economic policies, presiding over a policy of nationalising major industries and utilities including the Bank of England, coal mining, the steel industry, electricity, gas, and inland transport (including railways, road haulage and canals). It developed and implemented the "cradle to grave" welfare state conceived by the economist William Beveridge. To this day, most people in the United Kingdom see the 1948 creation of Britain's National Health Service (NHS) under health minister Aneurin Bevan, which gave publicly funded medical treatment for all, as Labour's proudest achievement. Attlee's government also began the process of dismantling the British Empire when it granted independence to India and Pakistan in 1947, followed by Burma (Myanmar) and Ceylon (Sri Lanka) the following year. At a secret meeting in January 1947, Attlee and six cabinet ministers, including Foreign Secretary Ernest Bevin, decided to proceed with the development of Britain's nuclear weapons programme, in opposition to the pacifist and anti-nuclear stances of a large element inside the Labour Party.

thumb|upright|Aneurin Bevan speaking in October 1952
Labour went on to win the 1950 general election, but with a much-reduced majority of five seats. Soon afterwards, defence became a divisive issue within the party, especially defence spending (which reached a peak of 14% of GDP in 1951 during the Korean War),Clark, Sir George, Illustrated History Of Great Britain, (1987) Octopus Books straining public finances and forcing savings elsewhere. The Chancellor of the Exchequer, Hugh Gaitskell, introduced charges for NHS dentures and spectacles, causing Bevan, along with Harold Wilson (then President of the Board of Trade), to resign over the dilution of the principle of free treatment on which the NHS had been established.

In the 1951 general election, Labour narrowly lost to Churchill's Conservatives, despite receiving the larger share of the popular vote – its highest ever vote numerically. Most of the changes introduced by the 1945–51 Labour government were accepted by the Conservatives and became part of the "post-war consensus" that lasted until the late 1970s. Food and clothing rationing, however, still in place since the war, were swiftly relaxed, then abandoned from about 1953.Bew, Clement Attlee: The Man Who Made Modern Britain (2017).

 Post-war consensus (1951–1964) 
Following the defeat of 1951, the party spent 13 years in opposition. The party suffered an ideological split, between the party's left-wing followers of Aneurin Bevan (known as Bevanites) and the right-wing of the party following Hugh Gaitskell (known as Gaitskellites) while the postwar economic recovery and the social effects of Attlee's reforms made the public broadly content with the Conservative governments of the time. The ageing Attlee contested his final general election in 1955, which saw Labour lose ground, and he retired shortly after.

Under his replacement, Hugh Gaitskell, Labour appeared more united than before and had been widely expected to win the 1959 general election, but did not. Following this internal party infighting resumed, particularly over the issues of nuclear disarmament, Britain's entry into the European Economic Community (EEC) and Clause IV of the Labour Party Constitution, which was viewed as Labour's commitment to nationalisation which Gaitskell wanted scrapped. These issues would continue to divide the party for decades to come.

Gaitskell died suddenly in 1963, and this made way for Harold Wilson to lead the party.

 Wilson government (1964–1970) 

thumb|left|upright|Harold Wilson, Prime Minister (1964–1970 and 1974–1976)
A downturn in the economy and a series of scandals in the early 1960s (the most notorious being the Profumo affair) had engulfed the Conservative government by 1963. The Labour Party returned to government with a 4-seat majority under Wilson in the 1964 general election but increased its majority to 96 in the 1966 general election.

Wilson's government was responsible for a number of sweeping social and educational reforms under the leadership of Home Secretary Roy Jenkins such as the abolishment of the death penalty in 1964, the legalisation of abortion and homosexuality (initially only for men aged 21 or over, and only in England and Wales) in 1967 and the abolition of theatre censorship in 1968. Wilson's government also put heavy emphasis on expanding opportunities through education, and as such, comprehensive education was expanded and the Open University created.

Wilson's first period as Prime Minister coincided with a period of relatively low unemployment and economic prosperity, it was however hindered by significant problems with a large trade deficit which it had inherited from the previous government. The first three years of the government were spent in an ultimately doomed attempt to stave off devaluation of the pound. Labour went on to unexpectedly lose the 1970 general election to the Conservatives under Edward Heath.

 Spell in opposition (1970–1974) 
After losing the 1970 general election, Labour returned to opposition, but retained Harold Wilson as Leader. Heath's government soon ran into trouble over Northern Ireland and a dispute with miners in 1973 which led to the "three-day week". The 1970s proved a difficult time to be in government for both the Conservatives and Labour due to the 1973 oil crisis, which caused high inflation and a global recession.

The Labour Party was returned to power again under Wilson a few days after the February 1974 general election, forming a minority government with the support of the Ulster Unionists. The Conservatives were unable to form a government alone, as they had fewer seats despite receiving more votes numerically. It was the first general election since 1924 in which both main parties had received less than 40% of the popular vote and the first of six successive general elections in which Labour failed to reach 40% of the popular vote. In a bid to gain a majority, a second election was soon called for October 1974 in which Labour, still with Harold Wilson as leader, won a slim majority of three, gaining just 18 seats taking its total to 319.

 Majority to minority (1974–1979) 

For much of its time in office the Labour government struggled with serious economic problems and a precarious majority in the Commons, while the party's internal dissent over Britain's membership of the European Economic Community, which Britain had entered under Edward Heath in 1972, led in 1975 to a national referendum on the issue in which two thirds of the public supported continued membership. Harold Wilson's personal popularity remained reasonably high but he unexpectedly resigned as Prime Minister in 1976 citing health reasons, and was replaced by James Callaghan. The Wilson and Callaghan governments of the 1970s tried to control inflation (which reached 23.7% in 1975) by a policy of wage restraint. This was fairly successful, reducing inflation to 7.4% by 1978. However it led to increasingly strained relations between the government and the trade unions.

thumb|upright|James Callaghan, Prime Minister (1976–1979)
Fear of advances by the nationalist parties, particularly in Scotland, led to the suppression of a report from Scottish Office economist Gavin McCrone that suggested that an independent Scotland would be "chronically in surplus". By 1977 by-election losses and defections to the breakaway Scottish Labour Party left Callaghan heading a minority government, forced to do deals with smaller parties in order to govern. An arrangement negotiated in 1977 with Liberal leader David Steel, known as the Lib–Lab pact, ended after one year. Deals were then forged with various small parties including the Scottish National Party (SNP) and the Welsh nationalist Plaid Cymru, prolonging the life of the government.

The nationalist parties, in turn, demanded devolution to their respective constituent countries in return for their supporting the government. When referendums for Scottish and Welsh devolution were held in March 1979 the Welsh devolution referendum saw a large majority vote against, while the Scottish referendum returned a narrow majority in favour without reaching the required threshold of 40% support. When the Labour government duly refused to push ahead with setting up the proposed Scottish Assembly, the SNP withdrew its support for the government: this finally brought the government down as the Conservatives triggered a vote of confidence in Callaghan's government that was lost by a single vote on 28 March 1979, necessitating a general election.

By 1978, the economy had started to show signs of recovery, with inflation falling to single digits, unemployment falling, and living standards starting to rise during the year.A Short History of the Labour Party by Henry Pelling Labour's opinion poll ratings also improved, with most showing the party to be in the lead. Callaghan had been widely expected to call a general election in the autumn of 1978 to take advantage of the improving situation. In the event, he decided to gamble that extending the wage restraint policy for another year would allow the economy to be in better shape for a 1979 election. However this proved unpopular with the trade unions, and during the winter of 1978–79 there were widespread strikes among lorry drivers, railway workers, car workers and local government and hospital workers in favour of higher pay-rises that caused significant disruption to everyday life. These events came to be dubbed the "Winter of Discontent".

These industrial disputes sent the Conservatives now led by Margaret Thatcher into the lead in the polls, which led to Labour's defeat in the 1979 general election. The Labour vote held up in the election, with the party receiving nearly the same number of votes than in 1974. However, the Conservative Party achieved big increases in support in the Midlands and South of England, benefiting from both a surge in turnout and votes lost by the ailing Liberals.

 Opposition and internal conflict (1979–1994) 

thumb|left|upright|Michael Foot, Leader of  the Opposition (1980–1983)
After its defeat in the 1979 general election the Labour Party underwent a period of internal rivalry between the left represented by Tony Benn, and the right represented by Denis Healey. The election of Michael Foot as leader in 1980, and the leftist policies he espoused, such as unilateral nuclear disarmament, leaving the European Economic Community and NATO, closer governmental influence in the banking system, the creation of a national minimum wage and a ban on fox hunting led in 1981 to four former cabinet ministers from the right of the Labour Party (Shirley Williams, Bill Rodgers, Roy Jenkins and David Owen) forming the Social Democratic Party. Benn was only narrowly defeated by Healey in a bitterly fought deputy leadership election in 1981 after the introduction of an electoral college intended to widen the voting franchise to elect the leader and their deputy. By 1982, the National Executive Committee had concluded that the entryist Militant tendency group were in contravention of the party's constitution. The Militant newspaper's five member editorial board were expelled on 22 February 1983.

The Labour Party was defeated heavily in the 1983 general election, winning only 27.6% of the vote, its lowest share since 1918, and receiving only half a million votes more than the SDP-Liberal Alliance, which leader Michael Foot condemned for "siphoning" Labour support and enabling the Conservatives to greatly increase their majority of parliamentary seats.  The party manifesto for this election was termed by critics as "the longest suicide note in history".

thumb|upright|Neil Kinnock, Leader of the Opposition (1983–1992)
Foot resigned and was replaced as leader by Neil Kinnock, with Roy Hattersley as his deputy. The new leadership progressively dropped unpopular policies. The miners' strike of 1984–85 over coal mine closures, which divided the NUM as well as the Labour Party, and the Wapping dispute led to clashes with the left of the party, and negative coverage in most of the press. Tabloid vilification of the so-called loony left continued to taint the parliamentary party by association from the activities of "extra-parliamentary" militants in local government.

The alliances which campaigns such as Lesbians and Gays Support the Miners forged between lesbian, gay, bisexual, and transgender (LGBT) and labour groups, as well as the Labour Party itself, also proved to be an important turning point in the progression of LGBT issues in the UK. At the 1985 Labour Party conference in Bournemouth, a resolution committing the party to support LGBT equality rights passed for the first time due to block voting support from the National Union of Mineworkers.

Labour improved its performance in 1987, gaining 20 seats and so reducing the Conservative majority from 143 to 102. They were now firmly re-established as the second political party in Britain as the Alliance had once again failed to make a breakthrough with seats. A merger of the SDP and Liberals formed the Liberal Democrats. Following the 1987 election, the National Executive Committee resumed disciplinary action against members of Militant, who remained in the party, leading to further expulsions of their activists and the two MPs who supported the group. During the 1980s radically socialist members of the party were often described as the "loony left", particularly in the print media. The print media in the 1980s also began using the pejorative "hard left" to sometimes describe Trotskyist groups such as the Militant tendency, Socialist Organiser and Socialist Action. In 1988, Kinnock was challenged by Tony Benn for the party leadership. Based on the percentages, 183 members of parliament supported Kinnock, while Benn was backed by 37. With a clear majority, Kinnock remained leader of the Labour Party.

In November 1990 following a contested leadership election, Margaret Thatcher resigned as leader of the Conservative Party and was succeeded as leader and Prime Minister by John Major. Most opinion polls had shown Labour comfortably ahead of the Tories for more than a year before Thatcher's resignation, with the fall in Tory support blamed largely on her introduction of the unpopular poll tax, combined with the fact that the economy was sliding into recession at the time. The change of leader in the Tory government saw a turnaround in support for the Tories, who regularly topped the opinion polls throughout 1991 although Labour regained the lead more than once.

The "yo-yo" in the opinion polls continued into 1992, though after November 1990 any Labour lead in the polls was rarely sufficient for a majority. Major resisted Kinnock's calls for a general election throughout 1991. Kinnock campaigned on the theme "It's Time for a Change", urging voters to elect a new government after more than a decade of unbroken Conservative rule. However, the Conservatives themselves had undergone a change of leader from Thatcher to Major and replaced the Community Charge. From the outset, it was clearly a well-received change, as Labour's 14-point lead in the November 1990 "Poll of Polls" was replaced by an 8% Tory lead a month later.

The 1992 general election was widely tipped to result in a hung parliament or a narrow Labour majority, but in the event, the Conservatives were returned to power, though with a much-reduced majority of 21.1992: Tories win again against odds  BBC News, 5 April 2005 Despite the increased number of seats and votes, it was still an incredibly disappointing result for supporters of the Labour party. For the first time in over 30 years there was serious doubt among the public and the media as to whether Labour could ever return to government.

Kinnock then resigned as leader and was succeeded by John Smith. Once again the battle erupted between the old guard on the party's left and those identified as "modernisers".  The old guard argued that trends showed they were regaining strength under Smith's strong leadership.  Meanwhile, the breakaway SDP merged with the Liberal Party. The new Liberal Democrats seemed to pose a major threat to the Labour base. Tony Blair (the Shadow Home Secretary) had a different vision to traditional Labour politics. Blair, the leader of the "modernising" faction, argued that the long-term trends had to be reversed, arguing that the party was too locked into a base that was shrinking, since it was based on the working-class, on trade unions, and on residents of subsidised council housing. Blair argued that the rapidly growing middle class was largely ignored, as well as more ambitious working-class families. Blair said that they aspired to become middle-class and accepted the Conservative argument that traditional Labour was holding ambitious people back to some extent with higher tax policies. To present a fresh face and new policies to the electorate, New Labour needed more than fresh leaders; it had to jettison outdated policies, argued the modernisers.David Butler and Dennis Kavanagh, The British general election of 1997 (1997) pp 46–67. The first step was procedural, but essential. Calling on the slogan, "One Member, One Vote" Blair (with some help from Smith) defeated the union element and ended block voting by leaders of labour unions. Blair and the modernisers called for radical adjustment of Party goals by repealing "Clause IV", the historic commitment to nationalisation of industry. This was achieved in 1995.

Black Wednesday in September 1992 damaged the Conservative government's reputation for economic competence, and by the end of that year, Labour had a comfortable lead over the Tories in the opinion polls. Although the recession was declared over in April 1993 and a period of strong and sustained economic growth followed, coupled with a relatively swift fall in unemployment, the Labour lead in the opinion polls remained strong. However, Smith died from a heart attack in May 1994.

 New Labour (1994–2010) 

thumb|left|upright|Tony Blair, Prime Minister (1997–2007)
Tony Blair continued to move the party further to the centre, abandoning the largely symbolic Clause Four at the 1995 mini-conference in a strategy to increase the party's appeal to "middle England". More than a simple re-branding, however, the project would draw upon the Third Way strategy, informed by the thoughts of the British sociologist Anthony Giddens.

New Labour was first termed as an alternative branding for the Labour Party, dating from a conference slogan first used by the Labour Party in 1994, which was later seen in a draft manifesto published by the party in 1996, called New Labour, New Life For Britain. It was a continuation of the trend that had begun under the leadership of Neil Kinnock. New Labour as a name has no official status, but remains in common use to distinguish modernisers from those holding to more traditional positions, normally referred to as "Old Labour".

The Labour Party won the 1997 general election in a landslide victory with a parliamentary majority of 179; it was the largest Labour majority ever, and at the time the largest swing to a political party achieved since 1945. Over the next decade, a wide range of progressive social reforms were enacted, with millions lifted out of poverty during Labour's time in office largely as a result of various tax and benefit reforms.

Among the early acts of Blair's government were the establishment of the national minimum wage, the devolution of power to Scotland, Wales and Northern Ireland, major changes to the regulation of the banking system, and the re-creation of a citywide government body for London, the Greater London Authority, with its own elected-Mayor. Combined with a Conservative opposition that had yet to organise effectively under William Hague, and the continuing popularity of Blair, Labour went on to win the 2001 election with a similar majority, dubbed the "quiet landslide" by the media. In 2003 Labour introduced tax credits, government  top-ups to the pay of low-wage workers. A perceived turning point was when Blair controversially allied himself with US President George W. Bush in supporting the Iraq War, which caused him to lose much of his political support. The UN Secretary-General, among many, considered the war illegal and a violation of the UN Charter. The Iraq War was deeply unpopular in most western countries, with Western governments divided in their support and under pressure from worldwide popular protests. The decisions that led up to the Iraq war and its subsequent conduct were the subject of Sir John Chilcot's Iraq Inquiry (commonly referred to as the "Chilcot report").

In the 2005 general election, Labour was re-elected for a third term, but with a reduced majority of 66 and popular vote of only 35.2%, the lowest percentage of any majority government in British history. During this election, proposed controversial posters by Alastair Campbell where opposition leader Michael Howard and shadow chancellor Oliver Letwin, who are both Jewish, were depicted as flying pigs were criticised as being anti-Semitic. The posters were referring to the expression 'when pigs fly', to suggest that Tory election promises were unrealistic. In response, Campbell said that the posters were not in "any way shape or form" intended to be anti-Semitic.

thumb|upright|Gordon Brown, Prime Minister (2007–2010)
Blair announced in September 2006 that he would quit as leader within the year, though he had been under pressure to quit earlier than May 2007 in order to get a new leader in place before the May elections which were expected to be disastrous for Labour.I will quit within a year – Blair  BBC News, 7 September 2007 In the event, the party did lose power in Scotland to a minority Scottish National Party government at the 2007 elections and, shortly after this, Blair resigned as Prime Minister and was replaced by his Chancellor, Gordon Brown. Although the party experienced a brief rise in the polls after this, its popularity soon slumped to its lowest level since the days of Michael Foot. During May 2008, Labour suffered heavy defeats in the London mayoral election, local elections and the loss in the Crewe and Nantwich by-election, culminating in the party registering its worst ever opinion poll result since records began in 1943, of 23%, with many citing Brown's leadership as a key factor. Membership of the party also reached a low ebb, falling to 156,205 by the end of 2009: over 40 per cent of the 405,000 peak reached in 1997 and thought to be the lowest total since the party was founded.

Finance proved a major problem for the Labour Party during this period; a "cash for peerages" scandal under Blair resulted in the drying up of many major sources of donations. Declining party membership, partially due to the reduction of activists' influence upon policy-making under the reforms of Neil Kinnock and Blair, also contributed to financial problems. Between January and March 2008, the Labour Party received just over £3 million in donations and were £17 million in debt, compared to the Conservatives' £6 million in donations and £12 million in debt. These debts eventually mounted to £24.5 million, and were finally fully repaid in 2015.

In the 2010 general election on 6 May that year, Labour with 29.0% of the vote won the second largest number of seats (258). The Conservatives with 36.5% of the vote won the largest number of seats (307), but no party had an overall majority, meaning that Labour could still remain in power if they managed to form a coalition with at least one smaller party.UK election results: data for every candidate in every seat  The Guardian (London), 7 May 2010 However, the Labour Party would have had to form a coalition with more than one other smaller party to gain an overall majority; anything less would result in a minority government. On 10 May 2010, after talks to form a coalition with the Liberal Democrats broke down, Brown announced his intention to stand down as Leader before the Labour Party Conference but a day later resigned as both Prime Minister and party leader.

 Opposition and internal conflict (2010–present) 

thumb|left|upright|Ed Miliband, Leader of the Opposition (2010–2015)
Harriet Harman became the Leader of the Opposition and acting Leader of the Labour Party following the resignation of Gordon Brown on 11 May 2010, pending a leadership election subsequently won by Ed Miliband. Miliband emphasised "responsible capitalism" and greater state intervention to change the balance of the economy away from financial services. Tackling vested interests and opening up closed circles in British society were themes he returned to a number of times. Miliband also argued for greater regulation of banks and energy companies. He adopted the "One Nation Labour" branding in 2012. The Parliamentary Labour Party voted to abolish Shadow Cabinet elections in 2011, ratified by the National Executive Committee and Party Conference. Henceforth the leader of the party chose the Shadow Cabinet members.

The party's performance held up in the 2012 local elections, with Labour consolidating its position in the North and Midlands while also regaining some ground in Southern England. In Wales the party enjoyed good successes, regaining control of most Welsh councils lost in 2008, including Cardiff. In Scotland, Labour held overall control of Glasgow City Council despite some predictions to the contrary, and also enjoyed a +3.26 swing across Scotland. Results in London were mixed as Ken Livingstone lost the election for Mayor of London, but the party gained its highest ever representation in the Greater London Authority in the concurrent assembly election.

At a special conference held on 1 March 2014, the party reformed internal Labour election procedures, including replacing the electoral college system for selecting new leaders with a "one member, one vote" system following the recommendation of a review by former general-secretary Ray Collins. Mass membership would be encouraged by allowing "registered supporters" to join at a low cost as well as full membership. Members from the trade unions would also have to explicitly "opt in" rather than "opt out" of paying a political levy to Labour.

The party edged out the Conservatives in the 2014 European parliamentary election, winning 20 seats to the Conservatives' 19. However, the UK Independence Party won 24 seats. Labour also gained 324 councillors in the 2014 local elections held the same day on 22 May. In September 2014, Shadow Chancellor Ed Balls outlined his plans to cut the government's current account deficit, and the party carried these plans into the 2015 general election. Whereas Conservatives campaigned for a surplus on all government spending, including investment, by 2018–2019, Labour stated it would balance the budget, excluding investment, by 2020. The 2015 general election unexpectedly resulted in a net loss of seats, with Labour representation falling to 232 seats in the House of Commons. The party lost 40 of its 41 seats in Scotland in the face of record swings to the Scottish National Party. Although Labour gained more than 20 seats in England and Wales, mostly from the Liberal Democrats but also from the Conservative Party, it lost more seats to the Conservatives, including Ed Balls in Morley and Outwood, for net losses overall.

thumb|upright|Jeremy Corbyn, Leader of the Opposition (2015–2020)
After the 2015 general election, Miliband resigned as party leader and Harriet Harman again became acting leader. Labour held a leadership election in which Jeremy Corbyn, then a member of the Socialist Campaign Group, was considered a fringe hopeful when the contest began, receiving nominations from just 36 MPs, one more than the minimum required to stand, and the support of just 16 MPs. However, he benefited from a large influx of new members as well as new affiliated and registered supporters introduced under Miliband. He was elected leader with 60% of the vote and membership numbers continued to climb after the start of Corbyn's leadership.

Tensions soon developed in the parliamentary party over Corbyn's leadership. Following the referendum on EU membership more than two dozen members of the Shadow Cabinet resigned in late June 2016, and a no-confidence vote was supported by 172 MPs against 40 supporting Corbyn. In July 2016, a leadership election was called as Angela Eagle launched a challenge against Corbyn. She was soon joined by rival challenger Owen Smith, prompting Eagle to withdraw in order to ensure there was only one challenger on the ballot. In September 2016, Corbyn retained leadership of the party with an increased share of the vote. By the end of the contest, Labour's membership had grown to more than 500,000, making it the largest political party in terms of membership in Western Europe.

Following the party's decision to support the European Union (Notification of Withdrawal) Bill 2017, at least three shadow cabinet ministers, all representing constituencies which voted to remain in the EU, resigned from their position as a result of the party's decision to invoke Article 50 under the bill. 47 of 229 Labour MPs voted against the bill (in defiance of the party's three-line whip). Unusually, the rebel frontbenchers did not face immediate dismissal. According to the New Statesman, approximately 7,000 members of the Labour Party also resigned in protest over the party's stance, which was confirmed by senior Labour sources.

In April 2017, Prime Minister Theresa May called a snap election for June 2017. The Labour campaign focused on social issues like health care, education and ending austerity. Although Labour started the campaign as far as 20 points behind, it defied expectations by gaining 40% of the vote, its greatest share since 2001. The party made a net gain of 30 seats to reach 262 total MPs and with a swing of 9.6% achieved the biggest percentage-point increase in vote share in a single general election since 1945. Immediately following the election party membership rose by 35,000. This has partly been attributed to the popularity of its 2017 Manifesto that promised to scrap tuition fees, address public sector pay, make housing more affordable, end austerity, nationalise the railways and provide school students with free lunches.

Following the 2017 general election, the party faced internal pressure to shift its Brexit policy away from a soft Brexit and towards a second referendum, a position widely supported among the party membership. In response, Corbyn said at the 2018 Labour Party conference that he did not support a second referendum but would abide by the decision of members at the conference. The party conference decided to support a Brexit deal either negotiated by the Conservatives and meeting certain conditions or negotiated by Labour in government. The conference agreed to use all means to stop an unacceptable Brexit deal, including another referendum including an option to remain in the EU, as a last resort. A week after seven Labour MPs left the party in February 2019 to form The Independent Group, partly in protest over Labour's Brexit position, the Labour leadership said it would support another referendum "as a final resort in order to stop a damaging Tory Brexit being forced on the country". TIG later rebranded as Change UK, and all of the defecting MPs were defeated in the 2019 general election, losing their seats.

From 2016, the Labour Party has faced criticism for failing to deal with antisemitism. Criticism was also personally levelled at Corbyn. The Chakrabarti Inquiry found instances of "toxic atmosphere" but exonerated the party of widespread antisemitism. The findings of this report were brought into question as Shami Chakrabarti knew she was set to receive a peerage and promptly joined Corbyn's shadow cabinet. A series of high profile cases involved Ken Livingstone, Peter Willsman and Chris Williamson, all of whom left the party or were suspended over the issue. In 2018, the Party was divided over adopting the IHRA Working Definition of Antisemitism, prompting 68 rabbis from the Jewish community to criticise the leadership for ‘claiming to know what’s good for our community’. The issue has been cited by a number of MPs who left the party to set up Change UK. Later, Louise Ellman also left over the issue. During the 2019 general election, Chief Rabbi Ephraim Mirvis made an unprecedented intervention in politics, stating that antisemitism, "[a] new poison – sanctioned from the top – has taken root in the Labour Party". His comments were supported by the Archbishop of Canterbury, Justin Welby. Earlier in 2019, the independent equalities watchdog, the Equalities and Human Rights Commission launched an investigation into whether the Labour Party had "unlawfully discriminated against, harassed or victimised people because they are Jewish", following complaints by the Jewish Labour Movement and the Campaign Against Antisemitism. In 2020, the EHRC would find the Labour Party to have broken the law by "political interference in anti-Semitism complaints", "failure to provide adequate training to those handling anti-Semitism complaints" and "harassment, including the use of anti-Semitic tropes and suggesting that complaints of anti-Semitism were fake or smears".

The 2019 Labour Party Manifesto included policies to increase funding for health, negotiate a Brexit deal and hold a referendum giving a choice between the deal and remain, raise the minimum wage, stop the age pension age increase, nationalise key industries, and replace universal credit. Due to the plans to nationalise the "big six" energy firms, the National Grid, the water industry, Royal Mail, the railways and the broadband arm of BT, the 2019 manifesto was widely considered as the most radical in several decades, more closely resembling Labour's politics of the 1970s than subsequent decades. The 2019 general election saw labour win its lowest number of seats in a UK general election since 1935. At 32.2%, Labour's share of the vote was down around eight points on the 2017 general election and is lower than that achieved by Neil Kinnock in 1992, although it was higher than in 2010 and 2015. In the aftermath, opinions differed to why the Labour Party was defeated to the extent it was. The Shadow Chancellor John McDonnell largely blamed Brexit and the media representation of the party. Tony Blair argued that the party's unclear position on Brexit and the economic policy pursued by the Corbyn leadership were to blame.

thumb|left|upright|Keir Starmer, Leader of  the Opposition (2020–present)
Following Labour's heavy defeat in the 2019 general election, Jeremy Corbyn announced that he would stand down as Leader of the Labour Party. Starmer announced his candidacy in the ensuing leadership election on 4 January 2020, winning multiple endorsements from MPs as well as from the trade union Unison. He went on to win the leadership contest on 4 April 2020, beating rivals Rebecca Long-Bailey and Lisa Nandy, with 56.2% of the vote in the first round, and therefore also became Leader of the Opposition. In his acceptance speech, he said would refrain from "scoring party political points" and that he planned to "engage constructively with the government", having become Opposition Leader amid the COVID-19 pandemic. He appointed his Shadow Cabinet the following day, which included former leader Ed Miliband, as well as both of the candidates he defeated in the leadership contest. He also appointed Anneliese Dodds as Shadow Chancellor of the Exchequer, making her the first woman to serve in that position in either a ministerial or shadow ministerial position. 

During the April pandemic lockdown, Starmer warned that the government was "in danger of being slow on their exit strategy" and called for "a roadmap to lift restrictions in certain sectors of the economy". But, despite various criticisms, he said that "the government is trying to do the right thing. And in that, we will support them."

On 25 June 2020, Starmer sacked his shadow education secretary Rebecca Long-Bailey after she refused to delete a tweet that called the actress Maxine Peake an "absolute diamond" and shared an interview in The Independent in which Peake repeated an antisemitic conspiracy theory concerning Israeli police and the death of George Floyd. Text of the original Independent interview is available here via Pressreader.com . Starmer said that "restoring trust with the Jewish community is a number one priority." On 27 June, he replaced her with Kate Green.

After the Equalities and Human Rights Commission found the Labour Party guilty of three breaches of the Equality Act, Corbyn condemned antisemitism but claimed the problem had been 'dramatically overstated for political reasons by our opponents ... [and] much of the media'. Corbyn was suspended from the party before being reinstated by a subcommittee of the NEC. Starmer has chosen to withhold the Labour whip from Corbyn for three months, pending an investigation.

 Ideology 

Labour is considered to be a centre-left party. It was initially formed as a means for the trade union movement to establish political representation for itself at Westminster. The Labour Party only gained a "socialist" commitment with the original party constitution of 1918, but that "socialist" element, the original Clause IV, was seen by its strongest advocates as a straightforward commitment to the "common ownership", or nationalisation, of the "means of production, distribution and exchange". Although about a third of British industry was taken into public ownership after the Second World War and remained so until the 1980s, the right of the party were questioning the validity of expanding on this objective by the late 1950s. Influenced by Anthony Crosland's book The Future of Socialism (1956), the circle around party leader Hugh Gaitskell felt that the commitment was no longer necessary. While an attempt to remove Clause IV from the party constitution in 1959 failed, Tony Blair and the "modernisers" saw the issue as putting off potential voters,Martin Daunton "The Labour Party and Clause Four 1918–1995" , History Review 1995 (History Today website) and were successful 35 years later,Philip Gould The Unfinished Revolution: How New Labour Changed British Politics Forever, London: Hachette digital edition, 2011, p.30 (originally published by Little, Brown, 1998) with only limited opposition from senior figures in the party.John Rentoul Defining moment' as Blair wins backing for Clause IV" , The Independent, 14 March 1995

Historically influenced by Keynesian economics, the party favoured government intervention in the economy, and the redistribution of wealth. Taxation was seen as a means to achieve a "major redistribution of wealth and income" in the October 1974 election manifesto. The party also desired increased rights for workers, and a welfare state including publicly funded healthcare. From the late-1980s onwards, the party adopted free market policies, leading many observers to describe the Labour Party as social democratic or the Third Way, rather than democratic socialist. Other commentators go further and argue that traditional social democratic parties across Europe, including the British Labour Party, have been so deeply transformed in recent years that it is no longer possible to describe them ideologically as "social democratic", and claim that this ideological shift has put new strains on the Labour Party's traditional relationship with the trade unions. Within the party, differentiation was made between the social democratic and the socialist wings of the party, the latter often subscribed to a radical socialist, even Marxist, ideology.

Party electoral manifestos have not contained the term socialism since 1992. While affirming a commitment to democratic socialism, the new version of Clause IV no longer definitely commits the party to public ownership of industry and in its place advocates "the enterprise of the market and the rigour of competition" along with "high quality public services [...] either owned by the public or accountable to them". In more recent times, a limited number of MPs in the Socialist Campaign Group and the Labour Representation Committee have seen themselves as the standard bearers for the radical socialist tradition in contrast to the democratic socialist tradition represented by organisations such as Compass and the magazine Tribune. The group Progress, founded in 1996, represents the centrist position in the party and was opposed to the Corbyn leadership. In 2015, Momentum was created by Jon Lansman as a grass-roots left-wing organisation following Jeremy Corbyn's election as party leader. Rather than organising among the PLP, Momentum is a rank and file grouping with an estimated 40,000 members.Momentum: Corbyn-backing organisation now has 40,000 paying members, overtaking Green Party .

 Symbols 
Labour has long been identified with red, a political colour traditionally affiliated with socialism and the labour movement. Prior to the red flag logo, the party had used a modified version of the classic 1924 shovel, torch, and quill emblem. In 1924 a brand conscious Labour leadership had devised a competition, inviting supporters to design a logo to replace the 'polo mint' like motif that had previously appeared on party literature. The winning entry, emblazoned with the word "Liberty" over a design incorporating a torch, shovel and quill symbol, was popularised through its sale, in badge form, for a shilling. The party conference in 1931 passed a motion "That this conference adopts Party Colours, which should be uniform throughout the country, colours to be red and gold"."Labour Party Annual Conference Report", 1931, p. 233.

thumb|left|upright=0.6|The red flag, originally the official flag and symbol of the Labour Party
Since the party's inception, the red flag has been Labour's official symbol; the flag has been associated with socialism and revolution ever since the 1789 French Revolution and the revolutions of 1848. The red rose, a symbol of socialism and social democracy, was adopted as the party symbol in 1986 as part of a rebranding exercise and is now incorporated into the party logo.

The red flag became an inspiration which resulted in the composition of "The Red Flag", the official party anthem since its inception, being sung at the end of party conferences and on various occasions such as in Parliament in February 2006 to mark the centenary of the Labour Party's founding. It still remains in use, although attempts were made to play down the role of the song during New Labour. The song "Jerusalem", based on a William Blake poem, is also frequently sung.

 Constitution and structure 

The Labour Party is a membership organisation consisting of individual members and constituency Labour parties, affiliated trade unions, socialist societies and the Co-operative Party, with which it has an electoral agreement. Members who are elected to parliamentary positions take part in the Parliamentary Labour Party (PLP). Prior to Brexit in January 2020, members also took part in the European Parliamentary Labour Party (EPLP).

The party's decision-making bodies on a national level formally include the National Executive Committee (NEC), Labour Party Conference and National Policy Forum (NPF)—although in practice the Parliamentary leadership has the final say on policy. The 2008 Labour Party Conference was the first at which affiliated trade unions and Constituency Labour Parties did not have the right to submit motions on contemporary issues that would previously have been debated. Labour Party conferences now include more "keynote" addresses, guest speakers and question-and-answer sessions, while specific discussion of policy now takes place in the National Policy Forum.

The Labour Party is an unincorporated association without a separate legal personality, and the Labour Party Rule Book legally regulates the organisation and the relationship with members. The General Secretary represents the party on behalf of the other members of the Labour Party in any legal matters or actions.

 Membership and registered supporters 
thumb|upright=1.5|A graph showing Labour Party individual membership, excluding affiliated members and supporters (1928–2018)
In August 2015, prior to the 2015 leadership election, the Labour Party reported 292,505 full members, 147,134 affiliated supporters (mostly from affiliated trade unions and socialist societies) and 110,827 registered supporters; a total of about 550,000 members and supporters. , the party had approximately 552,000 full members, making it the largest political party in Western Europe. Consequently, membership fees became the largest component of the party's income, overtaking trade unions donations which were previously of most financial importance, making Labour the most financially well-off British political party in 2017.

In February 2019, leaked membership figures revealed a decline to 512,000. By July 2019, further leaked figures suggested the membership may have fallen to 485,000. By January 2020, Labour was revealed to have around 580,000 registered members, making it the largest political party anywhere in Europe.

The 2003 Labour Party Conference accepted legal advice that the party could not continue to prohibit residents of the province joining, and whilst the National Executive has established a regional constituency party it has not yet agreed to contest elections there.

 Trade union link 

thumb|left|upright=0.8|Unite the Union showing their support for the Labour party on their Leeds offices during the 2015 general election
The Trade Union and Labour Party Liaison Organisation is the co-ordinating structure that supports the policy and campaign activities of affiliated union members within the Labour Party at the national, regional and local level.

As it was founded by the unions to represent the interests of working-class people, Labour's link with the unions has always been a defining characteristic of the party. In recent years this link has come under increasing strain, with the RMT being expelled from the party in 2004 for allowing its branches in Scotland to affiliate to the left-wing Scottish Socialist Party.RMT 'breached' Labour party rules  BBC News, 27 January 2004 Other unions have also faced calls from members to reduce financial support for the PartyLabour's link to unions in danger  BBC News, 16 June 2004 and seek more effective political representation for their views on privatisation, public spending cuts and the anti-trade union laws. Unison and GMB have both threatened to withdraw funding from constituency MPs and Dave Prentis of UNISON has warned that the union will write "no more blank cheques" and is dissatisfied with "feeding the hand that bites us". Union funding was redesigned in 2013 after the Falkirk candidate-selection controversy. The Fire Brigades Union, which "severed links" with Labour in 2004, re-joined the party under Corbyn's leadership in 2015.

 European and international affiliation 
The Labour Party was a founder member of the Party of European Socialists (PES). The European Parliamentary Labour Party's 10 MEPs were part of the Socialists and Democrats (S&D), the second largest group in the European Parliament. The Labour Party was represented by Emma Reynolds in the PES presidency.

The party was a member of the Labour and Socialist International between 1923 and 1940.Kowalski, Werner. Geschichte der sozialistischen arbeiter-internationale: 1923–1940  Berlin: Dt. Verl. d. Wissenschaften, 1985 Since 1951, the party has been a member of the Socialist International, which was founded thanks to the efforts of the Clement Attlee leadership. In February 2013, the Labour Party NEC decided to downgrade participation to observer membership status, "in view of ethical concerns, and to develop international co-operation through new networks". Labour was a founding member of the Progressive Alliance international founded in co-operation with the Social Democratic Party of Germany and other social-democratic parties on 22 May 2013.
