Johnson's Brexit plan comes under attack from Westminster, Dublin and Brussels

The European Parliament's Brexit Steering Group issued its response to the proposals Thursday after being briefed by Michel Barnier, the EU's chief Brexit negotiator.

In their statement, the steering group said it did not find the latest British proposals acceptable in their current form as representing a basis for an agreement that the European Parliament would give consent.

"The proposals do not address the real issues that need to be resolved," the statement added, citing the all-island economy, the full respect of the Good Friday Agreement, and the integrity of the European Single Market.

The statement concluded: "While we remain open to workable, legally operable and serious solutions, the UK's proposals fall short and represent a significant movement away from joint commitments and objectives."
