Boris is enjoying a honeymoon as London Mayor, as Andrew Grice of The Independent writes on his politics blog.

Will it last? I fear that Boris Johnson’s critics are already repeating the mistake they made during the campaign, as I argue in a New Statesman column on the Mayoral race fallout.

Gleefully anticipating a gaffe-filled mayoralty that will wreck David Cameron’s project helps Johnson to set expectations very low. Johnson benefits as much as Ronald Reagan or George W Bush ever did from being seriously “misunderestimated”. Which other candidate would have got away with floundering and being roughly £100m out on their sums for buses in the televised mayoral debates?

But if he merely remembers to put his trousers on every morning and get to work, Johnson’s mayoralty will be acclaimed as a triumph. But the real test must be the same any other mayor would face: delivery. That – with Johnson presented as a hands-off “chairman of the board” – is truly a test of the Cameron project”.

Rather than expecting a total fiasco, we should be scrutinising what the Tory modernisers want to do with power.

Perhaps the (conservative) answer will be not very much at all.
