seats (but still substantially less than Labour and the Conservatives), and several small parties (some of them regional or nationalist) trailing far behind in the number of seats, although this changed in the 2015 general election. In the last few general elections, voter mandates for Westminster in the 30–40% ranges have been swung into 60% parliamentary majorities. No single party has won a majority of the popular vote since the Third National Government of Stanley Baldwin in 1935. On two occasions since World War II – 1951 and February 1974 – a party that came in second in the popular vote came out with the larger number of seats. Electoral reform for parliamentary elections have been proposed many times. The Jenkins Commission report in October 1998 suggested implementing the Alternative Vote Top-up (also called alternative vote plus or AV+) in parliamentary elections. Under this proposal, most MPs would be directly elected from constituencies by the alternative vote, with a number of additional members elected from "top-up lists." However, no action was taken by the Labour government at the time. There are several groups in the UK campaigning for electoral reform, including the Electoral Reform Society, Make Votes Count Coalition and Fairshare. The boundary commission for England has also suggested in its 2023 boundary review that constituency lines should be redrawn to allow constituencies to have a similar number of residents. The 2010 general election resulted in a hung parliament (no single party being able to command a majority in the House of Commons). This was only the second general election since World War II to return a hung parliament, the first being the February 1974 election. The Conservatives gained the most seats (ending 13 years of Labour government) and the largest percentage of the popular vote but fell 20 seats short of a majority. The Conservatives and Liberal Democrats entered into a new coalition government, headed by David Cameron. Under the terms of the coalition agreement, the government committed itself to hold a referendum in May 2011 on whether to change parliamentary elections from first-past-the-post to AV. Electoral reform was a major priority for the Liberal Democrats, who favour proportional representation but were able to negotiate only a referendum on AV (the alternative vote system is not a form of proportional representation) with the Conservatives. The coalition partners campaigned on opposite sides, with the Liberal Democrats supporting AV and the
