William has pre-wedding nerves with knocking knees

Asked what was worrying him most about the wedding,William,28,laughed and said,the whole thing.

I was telling everyone I did the rehearsal the other day and my knees started tapping quite nervously, he told reporters in comments broadcast on Friday.

It8217;s quite a daunting prospect but very exciting and I8217;m thoroughly looking forward to it but there8217;s still a lot of planning to be done in the last four weeks, he added.

About 1,900 people 8211; from family and friends to foreign dignitaries,diplomats,soldiers and charity workers 8211; have been invited to the service in Westminster Abbey on April 29.

A worldwide audience of hundreds of millions is expected to tune in for Britain8217;s biggest royal occasion since Charles8217; ill-starred wedding to Diana three decades ago.

William was interviewed at the RAF base in north Wales where he works as a search and rescue helicopter pilot.

He said he and Harry,his younger brother who served on the front line in Afghanistan,had pulled off an undercover operation for his stag do.

It8217;s quite good news always to outfox the media but it was a military operation and my brother and I are very proud of how it went, he said.

He laughed off questions about how bad a hangover he had suffered after the traditional bachelor party.

Harry said on Thursday that he never thought that William would take the plunge and marry long-term girlfriend Middleton.

William said he and Middleton enjoyed a low-profile existence on the remote isle of Anglesey.

The beach is here and the general life is great to settle in and knuckle down to a proper job. We are left alone,it8217;s good, he said.
