The Democratic Unionist Party (DUP) will vote against Rishi Sunak’s revised Brexit deal because it does not give Northern Ireland the right to escape EU law.
Parliament will vote on the Windsor framework on Wednesday, although to the dismay of some MPs the House of Commons will get only 90 minutes to debate the agreement.
The DUP confirmed on Monday that it would oppose the Government. Sir Jeffrey Donaldson, the party leader, said: “Whilst representing real progress the ‘brake’ does not deal with the fundamental issue which is the imposition of EU law by the Protocol.”
Conservative MPs from the European Research Group (ERG) are expected to deliver their verdict on Tuesday.
