Wedding bells for Prince William?

The Prince is rumoured to have proposed to girlfriend Kate Middleton and could tie the knot in November, according to a biographer well-connected to Buckingham Palaceu00a0u00a0

An engagement between Prince William and long-time girlfriend Kate Middleton could be announced in early June, according to speculation based on a gap in the Buckingham Palace diary.

It is thought the Prince (27) and Middleton (28) could finally tie the knot in November.

He is this year due to begin a three-year posting as an RAF Search and Rescue pilot, and has been training at RNAS Culdrose in Cornwall.

Love story
Kate Middleton met Prince William at University of St Andrews in 2001. They soon started a relationship, media attention quickly followed, and in 2005 her lawyer complained of harassment. In February 2006, it was announced that Middleton would receive her own 24-hour security detail supplied by the Royalty and Diplomatic Protection Department. This fueled further speculation that she and the Prince would soon be engaged, since she would not, otherwise, be entitled to this service.u00a0 In April 2007, it emerged that William and Middleton had split up. They continued to be friends, and later in 2007 the pair reunited.

Brown, a friend of the Prince's late mother, described Middleton as his "patient squeeze" and that a "high-placed source in royal circles" had suggested the dates had been blocked for the announcement.

"If so, a wedding itself would probably follow in November, like the wedding of Queen Elizabeth II and Prince Philip, who married at Westminster Abbey that cold, damp November day in 1947," she wrote.

Brown, a former editor of Vanity Fair, added, "The Queen and Prince Philip, moreover, are approaching two landmark moments -- Philip will be 90 in June 2011, and the Queen celebrates her diamond jubilee - 60 years on the throne - in Feb 2012.

Grandpa eager

"Their closeness to their grandson, especially Philip, makes them eager, I am told, to see William settled in matrimony."

A St James's Palace spokesman declined to comment, but a source said suggestions Buckingham Palace had cleared its diary were "wide of the mark".

However, a spokesman for Clarence House said today that both Prince William and the Prince of Wales will be carrying out public engagements on those days, while the Queen also has an official engagement on June 3.

Royal insiders insist the Prince has given no indication of his plans to take the plunge.
