Brexit Secretary Dominic Raab has resigned saying he “cannot in good conscience support” the UK’s draft Brexit agreement with the EU.
Theresa May announced on Wednesday evening that she had secured the backing of her cabinet for the agreement, after a five hour meeting.
But several ministers were understood to have spoken against it.
And there are suggestions of moves among Conservative backbenchers to force a no-confidence vote in her.
The prime minister is due to make a Commons statement on the Brexit agreement at 1030 GMT.
Mr Raab – a Leave supporter who was promoted to the cabinet to replace David Davis when he quit in protest at Mrs May’s Brexit plans – is among a group of senior ministers thought to be unhappy with the agreement.
