it's already started in France. Now Britain has to get busy in history class.
Prince Harry has apologised after being pictured on the front page of The Sun in a Nazi uniform which he wore to a fancy dress party.
The newspaper showed the Prince, with a cigarette and drink in hand, wearing a swastika armband.
The 20-year-old said: "I am very sorry if I caused any offence or embarrassment to anyone."
In a statement released by Buckingham Palace, he added: "It was a poor choice of costume and I apologise."
On Harry's shirt collar was the badge of Wehrmacht - the German defence force.
The Prince was at a fancy dress party in West Littleton, Wiltshire last Saturday for the 22nd birthday party of his friend Harry Meade.
