With such an aristocratic pedigree, dashing War Horse star Kit Harington would not be expected to have to shin up drainpipes in the dead of night.

But when 25-year-old Kit, who is descended from the 4th Earl of Dartmouth, locked himself out of his North London home, he decided to break in.

Alas, the exercise didn’t quite go to plan. ‘I left my keys in the house, so after a drunken night out I tried to climb up to the first-floor window, but I fell backwards and broke my ankle in four places,’ says the actor, who is on crutches.

Kit was among guests at a party for private member’s club Omega House at Soho’s House of St Barnabas.

‘The doctors asked me if I’d been caught with another man’s wife and had to jump out of the window,’ he says. ‘I had to say no, but that would have been far more exciting.’
