Princes William and Harry were ushers at the wedding of Captain van Cutsem and Alice Hadden-Paton, an events organiser.

The 31-year-old groom is a life guard in the Household Cavalry, while his new wife Alice, 25, works as an events manager.

Her brother Harry Hadden-Paton has made a name for himself as a West End actor. The wedding of Nicholas and Alice is thought to have caught William off guard.
