The MP who will succeed Edwin Poots says his first priority will be to press the PM about the Irish Sea border
Sir Jeffrey Donaldson has promised to use his leadership of the Democratic Unionist party (DUP) to campaign against the Northern Ireland protocol.
The Lagan Valley MP aimed the volley at the British government and European Union on Tuesday after becoming the only candidate to succeed Edwin Poots, who resigned as DUP leader last week.
