UKIP, the third-largest party in 2015 by number of votes, saw its share of the vote reduced from 12.6% to 1.8% and lost its only seat. The Liberal Democrats made a net gain of four seats. The SNP, which had won 56 of the 59 Scottish seats at the previous general election in 2015, lost 21. The Scottish National Party (SNP) and the Liberal Democrats, the third- and fourth-largest parties, both lost vote share media coverage characterised the result as a return to two-party politics.

This was the closest result between the two major parties since February 1974 and their highest combined vote share since 1970. It was the first election in which the Tories had a net loss of seats or Labour had a net gain of seats since 1997. In a surprising result, the Conservative Party made a net loss of 13 seats despite winning 42.4% of the vote (its highest share of the vote since 1983), whereas Labour made a net gain of 30 seats with 40.0% (its highest vote share since 2001). From a 21-point lead, the Conservatives' lead began to diminish in the final weeks of the campaign. Opinion polls had consistently shown strong leads for the Conservatives over Labour. May said that she hoped to secure a larger majority to 'strengthen hand' in the forthcoming Brexit negotiations. Under the Fixed-term Parliaments Act 2011 an election had not been due until May 2020, but Prime Minister Theresa May's call for a snap election was ratified by the necessary two-thirds vote in the House of Commons on 19 April 2017. It was the first general election to be contested by either May or Corbyn May had succeeded David Cameron following his resignation as prime minister the previous summer, Corbyn had succeeded Ed Miliband who resigned following Labour's failure to win the general election two years earlier. The Conservative Party, which had governed as a senior coalition partner from 2010 and as a single-party majority government from 2015, was defending a working majority of 17 seats against the Labour Party, the official opposition led by Jeremy Corbyn. The governing Conservative Party remained the largest single party in the House of Commons but lost its small overall majority, resulting in the formation of a Conservative minority government with a confidence-and-supply agreement with the Democratic Unionist Party (DUP) of Northern Ireland.

The 2017 United Kingdom general election was held on Thursday, 8 June 2017, two years after the previous general election in 2015 and was the first to be held on a day which did not coincide with any local elections since 1992.
