2015 United Kingdom General Election

The 2015 United Kingdom general election was held on Thursday, 7 May 2015 to elect 650 members to the House of Commons. It was the first and only general election held at the end of a Parliament under the Fixed-term Parliaments Act 2011. Local elections took place in most areas on the same day.

Polls and commentators had predicted the outcome would be too close to call and would result in a second consecutive hung parliament whose composition would be either similar to or more complicated than the 2010 general election. Opinion polls were eventually proven to have underestimated the Conservative vote as the party, having governed in coalition with the Liberal Democrats since 2010, won 330 seats and 36.9% of the vote share, giving them a small overall majority of 12 seats (including Speaker John Bercow—ten seats without him) and their first outright win since 1992. It therefore won a mandate to govern alone with David Cameron continuing as Prime Minister.

The Labour Party, led by Ed Miliband, who had succeeded Gordon Brown following his resignation after defeat the 2010 general election following 13 years in Government, saw a small increase in its share of the vote to 30.4%; but incurred a net loss of seats to return 232 MPs. This was its lowest seat tally since the 1987 general election. Several senior Labour Shadow Cabinet members, notably Ed Balls, Douglas Alexander, and Scottish Labour leader Jim Murphy, were defeated.

The Scottish National Party, enjoying a surge in support after the 2014 Scottish independence referendum (which saw the majority of voters in Scotland to reject independence and stay as part of the United Kingdom), won a landslide victory in Scotland at the expense of Labour; who had dominated Scottish politics in terms of numbers of seats since 1964. The SNP won all but three of the 59 Scottish seats to become the third-largest party in the Commons.

The Liberal Democrats, led by outgoing Deputy Prime Minister Nick Clegg, had their worst result since their formation in 1988, losing all but eight of their 57 seats, with Cabinet ministers Vince Cable, Ed Davey and Danny Alexander losing their seats, although Clegg himself managed to retain his seat. UKIP came third in terms of votes with a 12.6% but won only a single seat, with party leader Nigel Farage failing to win the seat of South Thanet; but finished in a close second to the Conservatives in his most successful election result to date. The Green Party won its highest-ever share of the vote with 3.8%, and retained their only seat. Ed Miliband and Jim Murphy both resigned from the Leadership of the Labour Party, as did Clegg for the Liberal Democrats. In Northern Ireland, the Ulster Unionist Party returned to the Commons with two MPs after a five-year absence, while the Alliance Party lost its only seat despite an increase in total vote share.

The election is in retrospect considered to have begun a political realignment in the UK's electoral politics, marking the end of the traditional three-party domination seen for most of the previous century. The Scottish National Party began its domination of Scottish representation in Westminster (having already begun dominating elections to the Scottish Parliament since 2007). It also saw one of the last public appearances of former Liberal Democrat leader Charles Kennedy who lost his seat in Ross, Skye and Lochaber to the Scottish Nationalist Ian Blackford, before his death on 1 June.

Other notable members that stepped down at this election included: Former Chancellor of the Exchequer Alistair Darling, Frank Dobson, former Conservative leader William Hague, former Liberal Democrat leader Menzies Campbell and Malcolm Rifkind. Notable newcomers to the House of Commons included future Chancellor of the Exchequer and Prime Minister Rishi Sunak, future Labour Party leader Keir Starmer and future Labour deputy leader Angela Rayner. Another future Prime Minister, Boris Johnson, who previously stepped down in 2008 to serve as the Mayor of London returned to Parliament as the MP for Uxbridge and South Ruislip.

Election process

The Fixed-term Parliaments Act 2011 (as amended by the Electoral Registration and Administration Act 2013) led to the dissolution of the 55th Parliament on 30 March 2015 and the scheduling of the election on 7 May, the House of Commons not having voted for an earlier date. There were local elections on the same day in most of England, with the exception of Greater London. No other elections were scheduled to take place in Scotland, Wales or Northern Ireland, apart from any local by-elections.

All British, Irish and Commonwealth citizens over the age of 18 on the date of the election were permitted to vote. In general elections, voting takes place in all parliamentary constituencies of the United Kingdom to elect members of parliament (MPs) to seats in the House of Commons, the dominant (historically termed the lower) house of Parliament. Each parliamentary constituency of the United Kingdom elects one MP to the House of Commons using the "first-past-the-post" system. If one party obtains a majority of seats, then that party is entitled to form the Government. If the election results in no single party having a majority, then there is a hung parliament. In this case, the options for forming the Government are either a minority government or a coalition government.

Although the Conservative Party planned the number of parliamentary seats to be reduced from 650 to 600, through the Sixth Periodic Review of Westminster constituencies under the Parliamentary Voting System and Constituencies Act 2011, the review of constituencies and reduction in seats was delayed by the Electoral Registration and Administration Act 2013 amending the 2011 Act. The next boundary review was set to take place in 2018; thus, the 2015 general election was contested using the same constituencies and boundaries as in 2010. Of the 650 constituencies, 533 were in England, 59 in Scotland, 40 in Wales and 18 in Northern Ireland.

In addition, the 2011 Act mandated a referendum in 2011 on changing from the current first-past-the-post voting system to an alternative vote (instant-runoff) system for elections to the Commons. The Conservative–Liberal Democrat coalition agreement committed the coalition government to such a referendum. The referendum was held in May 2011 and resulted in the retention of the existing voting system. Before the previous general election the Liberal Democrats had pledged to change the voting system, and the Labour Party pledged to have a referendum about any such change. The Conservatives, however, promised to keep the first-past-the-post system, but to reduce the number of constituencies by 10%. Liberal Democrat plans were to reduce the number of MPs to 500, and for them to be elected using a proportional system.

Ministers increased the amount of money that parties and candidates were allowed to spend on the election by 23%, a move decided against Electoral Commission advice. The election saw the first cap on spending by parties in individual constituencies during the 100 days before Parliament's dissolution on 30 March: £30,700, plus a per-voter allowance of 9p in county constituencies and 6p in borough seats. An additional voter allowance of more than £8,700 is available after the dissolution of Parliament. UK political parties spent £31.1m in the 2010 general election, of which the Conservative Party spent 53%, the Labour Party spent 25% and the Liberal Democrats 15%.

This was the first UK general election to use individual rather than household voter registration.

Date of the election

An election is called following the dissolution of the Parliament of the United Kingdom. The 2015 general election was the first to be held under the provisions of the Fixed-term Parliaments Act 2011. Prior to this, the power to dissolve Parliament was a royal prerogative, exercised by the sovereign on the advice of the prime minister. Under the provisions of the Septennial Act 1716, as amended by the Parliament Act 1911, an election had to be announced on or before the fifth anniversary of the beginning of the previous parliament, barring exceptional circumstances. No sovereign had refused a request for dissolution since the beginning of the 20th century, and the practice had evolved that a prime minister would typically call a general election to be held at a tactically convenient time within the final two years of a Parliament's lifespan, to maximise the chance of an electoral victory for his or her party.

Prior to the 2010 general election, the Labour Party and the Liberal Democrats pledged to introduce fixed-term elections. As part of the Conservative–Liberal Democrat coalition agreement, the Cameron ministry agreed to support legislation for fixed-term Parliaments, with the date of the next general election being 7 May 2015. This resulted in the Fixed-term Parliaments Act 2011, which removed the prime minister's power to advise the monarch to call an early election. The Act only permits an early dissolution if Parliament votes for one by a two-thirds supermajority, or if a majority of MPs pass a vote of no confidence and no new government is subsequently formed within 14 days. However, the prime minister had the power, by order made by Statutory Instrument under section 1(5) of the Fixed-term Parliaments Act 2011, to fix the polling day to be up to two months later than 7 May 2015. Such a Statutory Instrument must be approved by each House of Parliament. Under section 14 of the Electoral Registration and Administration Act 2013, the Fixed-term Parliaments Act 2011 was amended to extend the period between the dissolution of Parliament and the following general election polling day from 17 to 25 working days. This had the effect of moving forward the date of the dissolution of the Parliament to 30 March 2015.

MPs not standing for re-election

While at the previous election there had been a record 148 MPs not standing for re-election, the 2015 election saw 90 MPs standing down. These comprised 38 Conservative, 37 Labour, 10 Liberal Democrat, 3 Independent, 1 Sinn Féin and 1 Plaid Cymru MP. The highest-profile members of parliament leaving were: Gordon Brown, a former Prime Minister, Leader of the Labour Party (both 2007–2010) and Chancellor of the Exchequer (1997–2007); and William Hague, the outgoing First Secretary of State and Leader of the House of Commons and former Foreign Secretary (2010–2014), Leader of the Conservative Party and Leader of the Opposition (both 1997–2001). Alongside Brown and Hague, 17 former cabinet ministers stood down at the election, including Stephen Dorrell, Jack Straw, Alistair Darling, David Blunkett, Sir Malcolm Rifkind and Dame Tessa Jowell. The highest profile Liberal Democrat to stand down was former leader Sir Menzies Campbell, while the longest-serving MP (the " Father of the House") Sir Peter Tapsell also retired, having served from 1959 to 1964 and then continuously since the 1966 general election.

Contesting political parties and candidates

Overview

, the deadline for standing for the general election, the Electoral Commission's Register of Political Parties included 428 political parties registered in Great Britain, and 36 in Northern Ireland. Candidates who did not belong to a registered party could use an "independent" label, or no label at all.

The Conservative Party and the Labour Party had been the two biggest parties since 1922, and had supplied all UK prime ministers since 1935. Polls predicted that these parties would together receive between 65% and 75% of votes, and would together win between 80% and 85% of seats; and that, as such, the leader of one of those parties would be the prime minister after the election. The Liberal Democrats had been the third party in the UK for many years; but as described by various commentators, other parties had risen relative to the Liberal Democrats since the 2010 election. ''The Economist'' described a "familiar two-and-a-half-party system" (Conservatives, Labour, and the Liberal Democrats) that "appears to be breaking down" with the rise of the United Kingdom Independence Party (UKIP), the Greens and the Scottish National Party (SNP). ''Newsnight''''Newsnight'', BBC2, 5 January 2015 and ''The Economist'' described the country as moving into a six-party system, with the Liberal Democrats, SNP, UKIP and Greens all being significant. Ofcom, in their role regulating election coverage in the UK, ruled that, for the general election and local elections in May 2015, the major parties in Great Britain were the Conservatives, Labour and Liberal Democrats, with UKIP a major party in England and Wales, the SNP a major party in Scotland, and Plaid Cymru (PC) in Wales, and that the Greens were not a major party.
