Prince William has been criticised for taking his £10 million military helicopter for a spin to his girlfriend Kate Middleton’s house.

The Prince practices a series of landings and take-offs in his £15,000-an-hour Chinook chopper in Kate’s back garden, just days after he was criticised for flying himself and his brother Harry to his cousin’s stag-do.

A military source told the News Of The World, " At a time when the Armed Forces are short of money and there is a lack of kit in Afghanistan and Iraq this is a total waste of money. He uses a Chinook to land in his girlfriend's garden then travels to a stag party in one. Where will it end?"

Aviation analyst and RAF-trained pilot Jon Lake added, “It's like a learner driver being given the keys to a Formula One car just because his father owns the racing team."
