It may only be three days since Jeremy Corbyn decisively won the Labour leadership election, and a day after his shadow cabinet was announced, but dividing lines are already being drawn by Corbyn’s new front bench.
New deputy leader Tom Watson has said there is “zero chance of a coup”, but having a new leader with such different policy ideas to many within the party is leading some to debate where the first rebellion will come from - and when.
There appears to be some disagreement even within the shadow cabinet: it has been widely reported Chris Bryant, who has taken the role of shadow commons leaders, originally turned down the defence role because of disagreements with Corbyn on defence policy.
So, just who is most likely to be first shadow minister to resign?
That would be shadow chancellor and would-be-overthrower of capitalism John McDonnell, according to Betway, at 11/4. He was followed by Corbyn's international development secretary Diane Abbott at 7/2. Leadership rival and shadow home secretary Andy Burnham follows at 11/2.
Lord Falconer might be the safest bet, given he’s offered at 20/1 - but all that could change soon, after he said today he would not stay in the shadow cabinet if the Labour leadership decided to campaign to leave the EU.
In an interview with World at One, Falconer said:
If the Labour Party adopts a position which says we might leave the EU and might argue against it then of course my position would become impossible at that point. But that's not the current position.
Meanwhile shadow foreign secretary Hilary Benn has issued a statement on Europe, saying Labour must not “walk away” from the EU.
And here was everyone thinking it was the Tories who would split over the European Union.
