Third meaningful vote may be postponed if there is insufficient support
Theresa May told MPs in a letter last night that she may postpone a third vote on her Brexit deal until after next week if there is insufficient support to see it passed.
Following talks with the EU this week, May will need to propose a new plan for negotiations unless the deal is agreed to before 12 April.
If the deal is passed, the deadline will be extended to 22 May.
In her letter she explained there were now four clear choices - voting in favour of her deal, agreeing to a longer extension, revoking Article 50 and leaving with no deal.
She emphasised that agreeing to a longer extension meant the UK partaking in the European elections, while she added that revoking Article 50 would "betray the result of the referendum".
While May looks to secure further support for her deal, Tom Watson, the deputy Labour leader, will speak at a march calling for a second referendum later today alongside London Mayor Sadiq Khan and Scotland First Minister Nicola Sturgeon.
The BBC have reported that Watson will support May's deal, provided it is then put to a public vote.
Campaigners and organisers say they expect hundreds of thousands of people to join the rally in central London.
The march also follows the news that a petition calling for Article 50 to be revoked had received a reported four million signatures.
