Northern Ireland has returned more nationalists than unionists for the first time after Democratic Unionist Party (DUP) deputy leader Nigel Dodds lost his seat at Westminster in the UK general election.

With Conservative Party leader Boris Johnson having secured a resounding victory, it has been a bad night for the DUP, which lost two seats plus its crucial influencing role supporting the Tory government.

The final seat of the 18 in Northern Ireland to declare was Fermanagh and South Tyrone, where Michelle Gildernew of Sinn Féin held the seat by a reported 57 votes from Tom Elliott of the Ulster Unionist Party.

The cross-community Alliance Party also took one seat, adding to the majority of anti-Brexit MPs.

Mr Dodds had become a power broker during the Brexit talks, when the DUP propped up the minority Conservative Party government after the UK general election of 2017.

His defeat completed a humiliation for the party, which said unionists were betrayed by the eventual deal Mr Johnson struck to leave the European Union.

Mr Dodds lost his seat to John Finucane, the son of one of the highest-profile victims of 30 years of sectarian bloodshed that was largely ended by the Belfast Agreement peace deal of 1998.

Mr Finucane is the first Sinn Féin MP returned in North Belfast. He was aided by a pact between Sinn Féin and the SDLP that saw the parties agree not to compete in some areas to avoid splitting the remain vote. Northern Ireland voted 56 per cent to 44 per cent to remain in the Brexit vote.
