The news that Sir Ian Blair resigned because he lost the confidence of Boris Johnson tells us two things. Firstly, that Sir Ian's limpet-like clinging to office demeaned him and the Met. He could have gone earlier and gone with honour. If he had taken the rap for any number of the failures he has been directly or indirectly responsible for, we could at least have some respect for him. I am afraid I think there is more to this resignation than meets the eye.
Sir Ian knew on 2 May that Boris had no confidence in him - he demonstrated it by treating Boris with contempt at his opening press conference, and has continued to do so ever since. Sir Ian clearly didn't reckon on the size of Boris's cojones.
And that's the second thing we have learned today - that Boris intends to see his agenda through and won't put up with people he either regards as incompetent or who stand in his way.
Having scored a brilliant goal today, Boris needs to go for the hatrick. And these are the two things he needs to do...
1. Scrap the western extention to the Congestion Charge zone.
2. Replace Peter Hendy as head of Transport for London.
Hendy is playing Boris for a fool. Everyone I speak to in City Hall sees it, but Boris still seems to think it's ok for Hendy to keep implementing Livingstone's transport policies. It isn't.
TfL needs a change of culture and Hendy is determined to resist it. It's one of the most bloated bureaucracies in government. Millions of pounds could be saved for the taxpayer by streamlining it and cutting out its excesses. Hendy attends meetings with Boris and spins him a load of cack. Boris needs to call his bluff and get rid of him.
UPDATE: Dan Hannan has MORE.
