Cameron must carry out a thorough reshuffle

With Parliament heading off for recess, politics will — barring some unforeseen event or the Eurozone crisis moving into one of its acute phases — be dominated by the Olympics for the next few weeks. David Cameron will be hoping that the global CEOs arriving in town will bring some good investment news with them. Boris Johnson, meanwhile, will revel in the global media attention. Indeed, Boris is already demonstrating an ability to brush off the organisational hiccups that other politicians can only envy.

But most ambitious Tories will spend the summer thinking about the reshuffle, currently pencilled in for the third of September ahead of a Tory parliamentary dinner on the fifth. There are siren voices suggesting that for reasons of party management, Cameron should not do too much: just retire a few of those who’ll be happy to leave and promote some of those who missed out in coalition.
