If Boris Johnson gave David Cameron a glowing vote of confidence, I must have missed it

Another day, another resignation. Events that would once have been seismic have become almost routine. Until we hear more from John Yates himself, I’m reluctant to say much more. Perhaps it’s better to take a step back and count the cost. The butcher’s bill so far: 2 senior policemen; 3 News International executives; 1 national newspaper.

Notably absent from that list so far is anyone from Her Majesty’s Government.

So perhaps it was inevitable that, when Boris Johnson called a press conference to discuss the Yates departure, someone (Michael Crick of Newsnight) asked the Mayor of London whether he believed that David Cameron himself should resign.

Mr Johnson replied:

I’m not here to discuss government appointments. Those questions you must address to government.

I don’t think there’s a very clear read across” [from Sir Paul Stephenson hiring Neil Wallis to Mr Cameron hiring Andy Coulson].

This is a matter you must address to No 10 Downing Street.

If Mr Johnson gave the Prime Minister a ringing endorsement or glowing vote of confidence, I’m afraid I missed it.
