MPs are getting ready for the second round of so-called "indicative" votes on EU withdrawal options, with cross-party support for softer versions of Brexit.

Westminster will look to find a consensus position after the first round of voting last week saw no option win a majority.

It follows Parliament wresting control of Commons business from Theresa May's government to hold the votes in dramatic scenes seven days ago.

MPs will take control of the Brexit agenda again on Monday to consider four proposals tabled by backbenchers, including one by SNP MP Joanna Cherry.

Alternatives on offer include a customs union with the EU, a second referendum on any deal and the "Norway plus" plan of single market membership and a customs arrangement with Brussels.

Cherry's motion proposes to give MPs a vote to block a no-deal Brexit at the last minute by demanding the UK revoke Article 50, cancelling the country's withdrawal from the EU.

Speaker John Bercow whittled down the options from the nine proposed, selecting four for voting, with results expected after 10pm.

If a majority coalesces behind any plan, MPs are expected to table legislation on Wednesday to try to force the government to act on it.

The move comes as the Prime Minister struggles to contain the rising tensions with her Cabinet as the clock counts down to the latest EU exit deadline on April 12.

Despite seeing the withdrawal agreement again defeated on Friday, May wants to bring her deal back to the Commons for a fourth time in a final bid to get it over the line.

And a letter to the Prime Minister signed by 170 Brexiteer Tory MPs and ministers has demanded Britain leave the EU by May 22 at the latest "without or without a deal".

Nicola Sturgeon has said her party's preference is for no Brexit, not soft Brexit, after she came under pressure last week for the SNP's decision not to back Tory MP Ken Clarke's customs union motion.

The First Minister said Cherry's proposal is the "most important" motion being tabled and added SNP MPs would decide how to vote when proposals are selected by Bercow later.

A petition calling on the UK to revoke Article 50 will also be debated in the House of Commons later on Monday after it topped six million signatures over the weekend.
