DUP set to vote against Brexit bill, raising fears some Tories will follow

MPs will debate the 'Stormont Brake' - a key measure in the Windsor Framework.

Under the brake, members of the Northern Ireland Assembly would be able to block EU regulations, but only in specific circumstances and with the EU able to take remedial action in response.

A senior DUP source told The Telegraph: "I would fully expect that we will be voting against that statutory instrument".

They have also said it would be unlawful for the UK government to veto the brake and that while the EU can ask for more information, it cannot stop the brake from being used. Downing Street has also highlighted that the statutory instrument will have the same status as the legislation implementing the Belfast Good Friday Agreement, and will codify the break into the Northern Ireland Act 1998..
