Britain might NOT leave the EU, David Davis 'privately admits': Brexit Secretary 'secretly says decision could be reversed' - undermining PM's New Year message promising to 'get on and deliver'

Theresa May faced a new Brexit rift with David Davis last night after claims that he has raised private doubts that the UK is certain to leave the EU.
The Prime Minister used her official New Year message to restate her determination to deliver on the result of the 2016 referendum vote.
She vowed to 'keep up progress in 2018' on the next stage of the EU exit talks, declaring: 'Making a success of Brexit is crucial.'
The vast majority of voters 'just want the Government to get on and deliver a good Brexit – and that's exactly what we are doing', she added.
But her defiant message was undermined by reports that Mr Davis told a private meeting it was still possible the decision to leave the EU could be reversed.
It follows a seminar hosted by Mr Davis at his Whitehall department shortly before Christmas, when he invited members of leading think-tanks to discuss the Government's success in getting an agreement with Brussels on moving to the next phase of Brexit talks.
