Theresa May has appealed to MPs' "patriotism" and urged them to cast aside their differences by voting for her Brexit deal to save her premiership.

In a bid to stave off a third heavy defeat, the Prime Minister writes in the Sunday Telegraph that MPs must "stand together as democrats and patriots" and support her Withdrawal deal.

MPs are likely to vote on the deal for the third time on Tuesday or Wednesday.

However, remainers are also plotting to scupper her Brexit plan with Labour planning to back a backbench amendment calling for a referendum on Mrs May's deal.

Mrs May's authority was dealt another blow on Saturday when Nick Boles, the Remain-supporting Tory MP, quit his local Tory association - although he will continue to support the Tories in the House of Commons.
