MP is seen as a moderate and bases appeal on opposing post-Brexit customs checks in Northern Ireland
Sir Jeffrey Donaldson has declared his candidacy to lead the Democratic Unionist party (DUP) and said he will seek to unite Northern Ireland’s unionists in a campaign against the Irish Sea border.
The Lagan Valley MP made the announcement on Monday, confirming his status as the favourite to replace Edwin Poots, a short-lived leader who resigned last week after an internal revolt.
