Bloomberg reports the headline, citing an anonymous European official

Latest word doing the rounds is that the EU is set to provide the UK with a letter on assurances for the backstop by next Monday, about 24 hours before the meaningful vote.

However, it must be said that these assurances will not be legally-binding as there has been no consultation with other EU27 members on the matter and these will merely come up to "clarifications" on the withdrawal agreement.

That said, unless European leaders surprise markets by offering an olive branch to Theresa May, she's still going to fall short of gathering enough support in next week's vote.
