Timing is everything in politics.
On Saturday morning it was being reported that DUP leader Arlene Foster had told Sky News that her party, albeit with great reluctance, would be helping to implement the NI Protocol (an integral part of Boris Johnson's Withdrawal Agreement) because it was now law and, in essence, there was nothing she could do about it.
Cue criticism of her across unionist parties, with many blaming the DUP for the mess unionism now found itself in and the very specific threat to Northern Ireland's constitutional position.
Criticism too from within the DUP, with some members quietly briefing that Foster had 'rolled over and given up the fight'.
An embarrassing position for her to be in just a few weeks after an enormous rebellion from her MLAs over a bill that appeared to make it easier for Sinn Fein to 'go on solo runs.'
What needs to be noted about Foster's interview was that the line on implementation of the Protocol wasn't just off the top of her head.
It will have been discussed with her advisers and senior party officials and there is nothing to suggest that any of them forewarned her about Johnson planning to throw a spanner in the works. So, either they didn't know, or, if they did, they didn't bother telling her.
On Sunday evening Sammy Wilson issued a statement (although not through the press office): 'The DUP will not accept the Withdrawal Agreement. We are still arguing that, in these negotiations, the Withdrawal Agreement must be scrapped or, at the very least, significantly changed. We have sought to persuade Conservative MPs that it is not only bad for Northern Ireland but ties the UK as a whole in to the influence of EU institutions. That remains our position.'
That read, as it was intended to read, as a warning shot over Foster's bows. She would probably have been prepared to brush it off (Sammy's maverick comments tend to embarrass rather than damage the party) had it not been for a breaking story from the Financial Times shortly after his intervention, which suggested Johnson was preparing to make changes to his own Withdrawal Agreement and the NI Protocol. Indeed, he might even opt for a no deal outcome if he didn't get his way.
This, of course, is hugely embarrassing for Foster, not least because it was clear that Johnson hadn't bothered telling her what he was planning to do; an extraordinary and seemingly deliberate insult by the Prime Minister.
It made her look weak and out of the loop to members of her own party; portraying her as someone willing to give up while the game was still in play. But it also leaves a bigger problem for the DUP (and all of unionism): given Johnson's track record does he deserve to be trusted right now? Let's face it, he has lied to and undermined the DUP on at least three occasions so far.
They never reached the 'chuckle brothers' level of bonhomie but, just three months ago, Arlene Foster and Michelle O'Neill were working well together at Stormont.
