Cameron to return to London as the riots spread

There we have it: David Cameron is to return to London tonight, and chair a meeting of Cobra in the morning. There was an inevitability to the decision even earlier today, with the news that both Theresa May and Boris Johnson had curtailed their own holidays. But the fact that the riots have spread — starting in Hackney this evening, and erupting even in Birmingham — served to underline the point.

It is the right decision, in any case. Cameron’s ability to control the situation may be limited, but his continued absence might only have inflamed things further. There are a lot of people scrabbling around for a grievance to bare and exploit tonight. The Prime Minister’s holiday can no longer be one.
