The Democratic Unionist party (DUP) is on track to lose three of its eight seats, which would leave Sinn Féin as the Northern Ireland party with most MPs.

The DUP lost the Lagan Valley seat vacated by its former leader, Jeffrey Donaldson, who faces sexual offence charges, and faced a stunning defeat in North Antrim where Ian Paisley lost a seat held by his family since 1970. It also lost South Antrim and had reduced majorities elsewhere.
