Tory Jacob Rees-Mogg has a big splash today after announcing he could finally back Theresa May's Brexit deal.
The ardent Catholic's confession - in a front-page apology in the Daily Mail - opens the door for the Prime Minister to give her deal one last Commons vote as soon as tomorrow.
But will he actually back it? There's one crucial catch to what the ringleader of Westminster's Brexiteers had to say.
Despite admitting there is now a choice between Mrs May's "bad" deal and no Brexit, Mr Rees-Mogg has not guaranteed his support.
Instead, he says, it will depend on whether the Northern Irish DUP come over to the same side.
He told the BBC this morning: "My only condition is the position of the DUP. I won't abandon the DUP because I think they are the guardians of the union of the United Kingdom."

Asked if they're coming aboard he added: "You'll have to ask them."
Mr Rees-Mogg previously claimed the deal would leave Britain "a slave state", but now has a front page story in the Daily Mail saying: "I apologise for changing my mind."
He says it is still a bad deal but adds he's willing to support it to avoid no Brexit at all.
Writing in the Daily Mail, Mr Rees-Mogg said: "I am now willing to support it if the Democratic Unionist Party does, and by doing so will be accused of infirmity of purpose by some and treachery by others.
"I have come to this view because the numbers in Parliament make it clear that all the other potential outcomes are worse and an awkward reality needs to be faced."

And he told the BBC: "Half a loaf is better than no bread."
Mr Rees-Mogg said that, while the deal is "deeply unsatisfying", it is the only way left of leaving the EU.
He added: "We are in a terrible constitutional muddle, we have a broken-down relationship between the executive and legislative.
"In those circumstances, the deal that Mrs May has got, with its many faults, is at least leaving the EU.
"I haven't changed my mind on the deal. The only way left of doing it (leaving the EU) is this deeply unsatisfying deal."
Boris Johnson also showed signs he could back the deal last night - but signalled he wanted a change of leadership.

He told an audience of Daily Telegraph readers: "If we vote it down again, for the third time, there is now, I think, an appreciable risk that we will not leave at all."
Stressing he was not there yet, he warned: "If people like me are to support this deal ... then we need to see the proof that the second phase of negotiations will be different from the first."
That will be interpreted as a call for Theresa May - who addresses Tory MPs at 5pm tonight - to name a date for her departure.
