Exit pollEdit

BBC News, ITV and Sky News all released an exit poll at 10pm. This poll predicted the Conservatives would be the largest party but lose their majority. Exit poll results:

  • Conservative Party - 314
  • Labour Party - 266
  • Scottish National Party - 34
  • Liberal Democrats - 14
  • Plaid Cymru - 3
  • Green Party - 1
  • UK Independence Party - 0
  • Others - 18

Final resultsEdit

The final results were very similar to the exit poll.

  • Conservative Party - 317 (down 13 seats)
  • Labour Party - 262 (up 30 seats)
  • Scottish National Party - 35 (down 21 seats)
  • Liberal Democrats - 12 (up 4 seats)
  • Plaid Cymru - 3 (no change)
  • Green Party - 1 (no change)
  • United Kingdom Independence Party - 0 (down 1 seat)
  • Others - 18

When the election was called the Conservative Party had a big lead in the polls and they were expected to win by a landslide. As the campaign went on the Labour Party closed the gap in the polls and the Conservatives lost their majority in the House of Commons.[3]

Important MPs who lost their seats include former Deputy Prime Minister Nick Clegg, former First Minister of Scotland Alex Salmond and The leader of the SNP in the House of Commons Angus Robertson.


  1. Given that Sinn Féin MPs do not take their seats and the Speaker and deputies do not vote, the number of MPs needed for a majority is, in practice, slightly lower. Sinn Féin won 7 seats, meaning a practical majority requires at least 320 MPs.
  2. Nicola Sturgeon sits as an MSP in the Scottish Parliament for Glasgow Southside. Before the election, the SNP delegation to the House of Commons had been led by Angus Robertson, MP for Moray, who lost his seat. Ian Blackford, MP for Ross, Skye and Lochaber, succeeded him.
  3. Gerry Adams sits as a TD in Dáil Éireann (lower house of the Irish Parliament) for Louth. The leader of the party in Northern Ireland, Michelle O'Neill, sits as an MLA in the Northern Ireland Assembly for Mid Ulster
  4. Sinn Féin MP's abstain from taking their seats in the British House of Commons.
  5. Arlene Foster sits as an MLA in the Northern Ireland Assembly for Fermanagh and South Tyrone. The party's leader in the Commons is Nigel Dodds, the MP for Belfast North
