It’s the G20 in Cannes this week. You’ve got to love the French for putting the summit in one of the most glamorous towns on the Cote d’Azur, but I suppose they’re versed in security down there, what with the film festival and all. I expect it’s pretty similar logistics ensuring Angelina Jolie and Brad Pitt can move safely from uber-yacht to La Croisette to the Carlton Hotel, as it will be for the 20 wealthiest nation heads of state to shuffle to the convention centre.
