Theresa May’s promise to step down last night if the deal passes looks to have unlocked substantially more support for the deal – a clear majority of the ERG have now come over including big beasts Boris and IDS – although a hard core of around 20-30 diggers-in remains. They are “still looking for a ditch in which to die”, in the words of one MP there…

May’s biggest hurdle now is the DUP, who put out a fresh statement last night confirming they still could not support the deal, before Nigel Dodds brutally put down any suggestion that they could abstain instead of voting against it:

Jacob Rees-Mogg, who has now been branded everything from “traitor” to “eurofederalist” after saying it’s May’s deal or no Brexit on Monday, reiterated his position on Peston last night that he will still vote against the deal unless the DUP are on board. However, he does suggest how domestic law could be used to address the DUP’s concerns. Will it be enough? We’ll find out soon enough…

UPDATE: It’s still a no from the DUP according to Laura Kuenssberg “For avoidance of doubt, DUP will vote against agreement tomorrow, party source says”
