STORY: Standing alongside European Commission President Ursula von der Leyen at a news conference in Windsor, Sunak said the two sides had agreed to ease trade rules for the British province and give its lawmakers more control over the laws they have to follow.

"I'm pleased to report that we have now made a decisive breakthrough," Sunak said, adding that they had agreed to change the original deal for Northern Ireland, known as the protocol, to create the "New Windsor Framework".

"This is the beginning of a new chapter in our relationship."
