DAVID CAMERON is a fan of skinny dipping, according to a the boss of one of the Prime Minister's favourite tourist spots.

Adrian Morrow, managing director of Glenarm Castle Estate, in Northern Ireland, said: “He was here a few years ago when he was a very quiet, reserved young chap.

“He stayed with ourselves. If I remember right he was skinny-dipping in the river.”

Downing Street immediately played down the claim but the PM did admit a love of swimming in the region.

In a speech to the Stormont Assembly Mr CAMERON SAID:  “I love coming here whether it's to see the opera... or to walk through the beautiful Glens of Antrim, or swim off the Atlantic coast.”
