Even when he’s on holiday, Richard Branson likes to fly. ‘I’m sorry I’m late. I’ve been heli-skiing with Holly and Sam and the weather was too good to stop,’ he explains as he arrives at the chalet near Calgary, in Canada, where he and his two children are staying for New Year. It’s late afternoon and Branson, who is usually pretty cheerful, is more upbeat than ever. It’s not just the mountain air, or the plush chalet he’s partying in — ‘it belongs to friends’ — or the fact that he, Holly and Sam are planning to become the first space tourists to fly on Virgin Galactic, Branson’s new spaceship, which is currently undergoing final tests in the US. Nor is it because he has just finished rebuilding his Great House on Necker Island, destroyed by fire in 2011, leaving the exclusive resort in good enough nick for him to invite Kate Moss to spend her 40th birthday there last week.
