Prince William's wedding nerves

Britain's Prince William was so nervous at his wedding rehearsal his knees started knocking.

The second in line to the throne will marry his long term girlfriend Kate Middleton at London's Westminster Abbey on April 29 and admitted with less than a month to go he is feeling the pressure.

He said: "I did the rehearsal the other day and my knees were tapping quite nervously so it's quite a daunting prospect but a very exciting one and I'm thoroughly looking forward to it. However, there is still a lot of planning to be done in the last four weeks."

However, before he can focus on his wedding to Kate, William has to think about his day job as a Royal Air Force (RAF) search and rescue pilot and he revealed he gets a great deal of satisfaction from being able to help those in need.

He explained to Britain's Daily Telegraph: "Every day you come into work and you don't know what's going to happen so it's quite exciting in that sense. However, it's great that you get to go out and save someone's life hopefully or at least that you can make a difference if they're in trouble.

"With the team environment in the cockpit it's a real family atmosphere. I'm incredibly proud to be working with the search and rescue team and fly with - in my opinion - some of the best pilots in the world."
