Results

About the election Short description of the context and results of the election.
The first elections after the Brexit referendum (see note) resulted in a hung parliament. Prime Minister Theresa May of the Conservative Party had called early elections, calling on voters' support for "a strong and stable government to get the best Brexit deal". The Conservative Party won the elections but lost the parliamentary majority. The Labour Party, led by Mr. Jeremy Corbyn, increased its share of seats from 232 to 262, while promising to work for "a jobs-first Brexit that allows us to upgrade our economy for the 21st century". Ms. May subsequently formed a minority government, with the support of the Democratic Unionist Party led by Ms. Arlene Foster. A record number of 208 women (up from 191) were elected to the House of Commons in 2017 (32% of MPs). During the election campaigning, the major parties focused more on social care and education than on Brexit. Two terror attacks occurred during the campaign - the Manchester Arena bombing on 22 May and the London Bridge attack on 4 June - pushing the security issue to the centre of the campaigning in run-up to the polling day. Note: A referendum on Brexit (merging of the words "Britain" and "exit") to decide whether the United Kingdom should leave or remain in the European Union was held in June 2016. Leave camps narrowly won the referendum. The then Prime Minister David Cameron (Conservative Party) resigned after the referendum and was succeeded by Ms. May in July of that year.
