An Army officer from the Highlands has told how he hit Prince William with a potato during a training exercise.
The Queen chats to her grandson at his passing out
David Robertson, from Inverness, received the Queen's Medal when he and William passed out at Sandhurst military academy.
Junior Under Officer Robertson, who is attached to the Royal Regiment of Scotland, threw the vegetable at the prince during a mock riot.
The 29-year-old was honoured for getting the best scores in his class.
'Story to tell'
Mr Robertson said: "I will be able to tell my grandchildren I hit the future monarch round the head with a 2lb potato.
"He loved it like anyone else would and started swinging the baton - a baton you get hit with if you get too close."
The Queen's Medal is awarded to the officer cadet who achieves the best scores in military, practical and academic studies.
Prince William also passed out at the parade and is set to follow his brother Harry into the Household Cavalry's Blues and Royals, with the aim of becoming a troop leader in an armoured reconnaissance unit.
