Prince William is set to propose to Kate Middleton, with a royal wedding predicted for 2009.
A British paper claims that the 25-year-old prince will propose to Middleton as soon as he finishes his training with the Royal Air Force and Royal Navy, late next year.
"We will know about an engagement sooner rather than later," a royal source told the newspaper.
