Prince William and Kate Middleton

Britain's Prince William and his fiancee Kate Middleton are to be married on April 29th at London's Westminster Abbey, in a ceremony that will be watched live on television by millions around the world.

The elder son of heir-to-the-throne Prince Charles and the late Princess Diana proposed to Middleton with the large blue oval sapphire and diamond engagement ring his mother once wore as Charles's 19-year-old fiancee.

"It's very special to me," William told reporters when announcing the engagement in November last year.
