British MPs will on Tuesday vote again on Prime Minister Theresa May's Brexit deal, making the historic decision whether to back her plan or risk a chaotic exit from the EU in less than three weeks time.
Two months ago, the House of Commons rejected the withdrawal agreement by a huge majority, and sent May back to renegotiate.
But European Union leaders have rejected her demands as impossible, and without a breakthrough in the next 24 hours, some MPs have warned another defeat is "inevitable".
Unless it negotiates a delay, Britain would then be on course to leave the EU after 46 years of membership with no plan on March 29, causing huge disruption on both sides.
British and European officials have continued their talks this weekend, and May is ready to make a last-minute visit to Brussels if needed.
In the absence of visible progress, she has sought to remind MPs of the stakes involved in rejecting her divorce agreement.
"Back it and the UK will leave the European Union. Reject it and no one knows what will happen," she said in a speech on Friday. "We may not leave the EU for many months. We may leave without the protections that the deal provides. We may never leave at all."
