The son of Queen Elizabeth II's daughter Princess Anne will marry a Canadian businesswoman, the palace announced.

Peter Phillips, 29, will marry his girlfriend, Autumn Kelly, Buckingham Palace said in a statement. The couple met at the Canadian Grand Prix in Montreal in 2003.

"The Princess Royal and Captain Mark Phillips are pleased to announce the engagement of their son Peter Phillips to Autumn, daughter of Mr. Brian and Mrs. Kitty Kelly," the palace said.

Phillips is 10th in line to the throne but holds no royal title and carries out no official royal duties. He works for the Royal Bank of Scotland.
