Theresa May is considering plans to allow MPs a vote on keeping Britain in a Customs Union as she refuses to quit as Prime Minister despite MPs and ministers urging her to stand down.

After Brussels rejected her request for a three month delay, Mrs May returned to the UK yesterday and began drawing up new plans for Brexit.

Under the latest proposals MPs will be offered "indicative votes" on a range of Brexit alternatives if, as anticipated, the Prime Minister's deal is defeated for a third time.

MPs will be asked to vote on membership of the Single Market and Customs Union as well as revoking Article 50 and holding a second referendum.

But her new plan immediately led to another backlash, with one minister warning it will "tip her over" and hasten her departure from office amid fears it will lead to a soft Brexit.

A succession of senior Tory MPs, including some the Prime Minister's own whips, have directly called on her to quit over the past fortnight amid anger over the Brexit delay.
