Prime Minister Theresa May has reportedly refused to approve a draft Brexit agreement with Brussels on Sunday night amid fears that her Cabinet would fail to back the plan.
The agreement was expected to be announced as soon as Monday but an 11th hour move by both the Prime Minister and Brexit Secretary have apparently expressed concerns about the backstop agreement with Northern Ireland.
It is understood unless the backstop agreement had a finite end date then neither Brexit-backing Cabinet Minister’s, nor the DUP would be willing to endorse the plan.
It is also being reported that Brexit Secretary Dominic Raab has rejected EU calls for the deal to be agreed in two parts; first the withdrawal and then new trade arrangements, amid fears that without a new framework the backstop could be triggered straight away.
Political agreement over the Chequers proposal has dogged the Government as both Brexiteers and Remainers alike view the plan as both unsatisfactory and unsellable.
On Sunday night political agreement over the wording of the backstop agreement had still not been reached and senior Brexiteers warned that even an agreement that included conditions may not be enough to assuage concerns.
The Prime Minister now faces the growing prospect of Cabinet resignations over the impasse.
