The British Prime Minister is to give Prince William and Kate Middleton a book on Anglesey as his Royal Wedding gift

David Cameron has revealed his wedding gift to Prince William and Kate Middleton is a book about Anglesey.

The Prime Minister said his present included "beautiful photographs" of the island, where the Prince is based as an RAF search and rescue helicopter pilot.

In an interview with US journalist Katie Couric on the CBS Evening News, Mr Cameron said he thought the couple had "probably got everything".

Explaining his choice of gift, he said: "He's currently serving in Anglesey, which is a small island off the coast of Wales where he does search and rescue, flies a helicopter - very brave. And I've got him a present to do with Anglesey."

He added: "It's a lovely book and beautiful photographs and things like that."

The Prime Minister said the royal wedding would provide "happiness and joy and light relief after some difficult times".

Asked what the event meant to him, he said: "I think British people... we feel very deeply about the monarchy and the institution, so it's that mixture of the good looking prince and the beautiful princess, but it's so much more than that. It's this institution that's helped bind the country together. And it's got this amazing history that goes way, way back."

He added the occasion was "an excuse for a bit of a party and some fun at the same time".

What will the British PM wear at the Royal Wedding?

The issue of the Prime Minister’s attire had become one of the most hotly-debated subjects in the build-up to the big day after Downing Street said he would be wearing a work-style suit.

He was said to be sensitive to opponents trying to portray him as “a toff”, following the publication of pictures of him wearing a white tie and tails when he was a member of the Bullingdon Club dining society at Oxford.

But after criticism on radio phone-in shows and in newspapers of his decision to dress down, The Telegraph has learnt that he will now wear a morning suit after all.
