LONDON (AP) -- Royal officials say Prince William and girlfriend Kate Middleton are engaged to be married.

Prince Charles' Clarence House office says the heir to the throne is "delighted to announce the engagement of Prince William to Miss Catherine Middleton."

The palace says they got engaged last month during a vacation in Kenya. They are due to marry next spring or summer in London.

The couple are both 28 and met more than eight years ago while students at the University of St. Andrews in Scotland.
