LONDON, - British Prime Minister Rishi Sunak's spokesperson on Tuesday urged lawmakers to back a major element of the new deal over post-Brexit trading arrangements in Northern Ireland, adding it was a good deal amid criticism from some Conservatives.

"The Stormont Brake is important and the most significant part of the framework, and we continue to urge parliamentarians to back it," the spokesperson said ahead of a vote on that aspect of the so-called Windsor Framework on Wednesday.

"I don't get into commenting on messages to Conservative MPs... But broadly this is a good deal for the people of Northern Ireland."
