Theresa May will be warned by senior Eurosceptic Cabinet ministers that leaving the EU without a deal will be better than giving in to Brussels' demands on Brexit.

Dominic Raab, the Brexit Secretary, and leading Eurosceptics including Andrea Leadsom and Liam Fox are expected to use a Cabinet meeting on Tuesday to warn the Prime Minister that the EU's demands are "totally unacceptable".

On Monday night they were due to meet for eve-of-Cabinet drinks at Dr Fox's office to discuss concerns that Brussels is refusing to back down over the issue of a customs "backstop" with the EU.

They were expected to be joined by Michael Gove, the Environment Secretary, Geoffrey Cox, the Attorney General and Penny Mordaunt, the International Development Secretary, who all fear Britain could be locked into a customs union with the EU.

It came as Michel Barnier, the EU's chief Brexit negotiator, was accused of attempting to force the Prime Minister's hand after reportedly suggesting that a deal was ready for Mrs May to present to Cabinet on Tuesday.
