Sinn Féin has become Northern Ireland’s largest party in Westminster after voters turned against the Democratic Unionist party and delivered a shock result that has been labelled the fall of the house of Paisley.

The DUP lost three of its eight Westminster seats in Thursday’s election, including the North Antrim stronghold held by Ian Paisley and before that his late father since 1970.
