Theresa May will continue to sell her Brexit withdrawal deal on Friday, as cabinet minister Michael Gove is understood to be considering quitting.
BBC political editor Laura Kuenssberg said she understood Mr Gove had rejected the PM’s offer to make him Brexit secretary, because Mrs May would not let him renegotiate the deal.
Dominic Raab quit the role on Thursday over “fatal flaws” in the agreement.
Mrs May says the deal “delivers what people voted for”.
But she was warned by one of her own backbenchers that it was “dead on arrival” and would never get the backing of MPs.
The government unveiled its long-awaited draft withdrawal agreement on Wednesday, which sets out the terms of the UK’s departure from the EU, over 585 pages.
The prime minister will answer callers’ questions about the plan on LBC radio on Friday morning.
