The Queen’s Platinum Jubilee pageant was officially launched last week, with a splashy press call in the Raphael Court of the V&A. I happen to be co-chair of the pageant, to be held in June next year, alongside the eventmeister Sir Michael Lockett. The Raphael Gallery felt like an appropriate setting, since the seven glorious cartoons, considered the most important Renaissance paintings outside the Vatican, belong to the Queen on longstanding loan.
