Boris Johnson's Deputy Simon Milton threatened to quit, if Tim Parker remained at City Hall, it was revealed today.
According to a senior member of the administration, Milton told the Mayor:
"He went to Boris and said, 'Parker is acting like he's the Mayor, not you. Either he goes or I do'
"So Boris was put in a position where he had to grasp the nettle, even though he didn't want to, because Boris hasn't learnt yet that in politics you can't be everyone's friend."
The Indy's detailed account of events leading up to the Parker resignation comes after a week of heavy briefing from all sides in the dispute.
And although other accounts have differed over whether Parker jumped or was pushed, the consistent impression is of an administration mired in rows, slanging matches, and political maneuvering.
One source close to the centre of power at City Hall told the Troll:
"Parker going won't be the end of this. They are still at each other's throats on the eighth floor and I wouldn't be surprised if more people ended up quitting. It's chaos frankly, and Boris has lost himself a lot of respect."
The furore over the Forensic Audit Panel and the farcical briefings about non-existent 'hidden wine cellars' are also a major source of tension at City Hall. Many staff continue to see them as little more than political 'stitch-ups.'
But beyond the internal politics of the last few months, there remains serious structural problems, which the removal of Parker has not solved. An ex-Tory Minister told the Indy:
"Boris's team is now overly represented by a group of undistinguished Tory councillors, all of them pretty low-grade, with the exception of Milton.
"The danger is Boris will let them have too much sway and they'll run a tame mayoralty which will miss the chance to do radical things.
"They'll muddle on as they've always done while Boris continues to amuse the nation. The other danger is that Boris will take on too much himself, particularly after saying that he's taking over as chair of TfL because the decisions are all political, and that's not his area of competence."
So as Boris enjoys headlines for promising to bring in the Olympics under budget (it's called a contingency) he should remember that there are big problems awaiting him in a small riverside office block back home.
