First, the important stuff. Mr Cameron and Barack Obama used a video conference on Thursday evening to impress upon Nicolas Sarkozy and Angela Merkel the need to sort out the eurozone crisis with a comprehensive package: the clock on that deal is now ticking.
Ms Merkel has told Mr Sarkozy she won’t be able to sign up to any deal until next Wednesday at the earliest, so a special second meeting of eurozone leaders has been fixed in Brussels for that day.
Of course Mr Cameron won’t be invited to that meeting, but it could still be awkward for the PM. As European leaders grapple with the economic fire raging across the English Channel, Mr Cameron will be heading to the other side of the world for a Commonwealth summit in Perth.
