Prince Philip would get into the trouble with his wife for playing a practical joke on his grandchildren which involved squirting mustard on the ceiling, William has revealed.

The prince recalled Philip’s sense of fun in a BBC One documentary being screened on Wednesday which features personal and poignant tributes to the duke, who died in April, from more than a dozen members of the royal family.
