by the Conservative leader Margaret Thatcher in 1979. The 97 net seat gains made by the Conservatives outdid their previous best gains total in 1950, when they gained 85. Labour's loss of 91 seats was worse than their previous greatest loss of seats, when they lost 77 seats in 1970. Of the 532 seats contested in England (a final seat, Thirsk and Malton, was contested on 27 May), the Conservatives won 298 seats and an absolute majority of 61 seats over all other parties combined, securing an average swing of 5.6% from Labour. Labour did poorly in many Southern areas, notably in the Eastern Region where they won only two of their 14 seats from 2005: Luton North and Luton South. Labour did, however, gain two seats: Bethnal Green and Bow and Chesterfield. The Conservatives made 95 of their gains in England, but they also suffered three losses, all to the Liberal Democrats. For the Liberal Democrats, their eight gains were overshadowed by their 12 losses – one to Labour and 11 to the Conservatives. None of Scotland's 59 seats changed hands and all were held by the same party that had won them at the 2005 election, with Labour regaining the two seats they had lost in by-elections since 2005. There was a swing to Labour from the Conservatives of 0.8% (with Labour increasing its share of the vote by 2.5% and the Conservatives increasing by just 0.9%) The Conservatives finished with just a single MP representing a Scottish constituency. Of the 40 seats contested in Wales, the Conservatives more than doubled their seats from three to eight, taking one from the Liberal Democrats and four from Labour. Welsh nationalist party Plaid Cymru's number of seats was reduced from three to two on the new seat boundaries, but they managed to gain one seat, Arfon, from Labour. Labour did, however, regain Blaenau Gwent, which had once been Labour's safest seat in Wales until it had been taken by an Independent, Peter Law, in 2005. Overall, Labour made a net loss of 4 seats but remained the biggest party, with 26. There were 18 seats contested in Northern Ireland. Both Irish nationalist parties, Sinn Féin and the Social Democratic and Labour Party (SDLP), held their seats. The unionist Democratic Unionist Party (DUP) and Ulster Unionist Party (UUP) (the latter in an electoral pact with the Conservatives), lost one seat each.
