US President Barack Obama and his wife Michelle with the Queen and Prince Philip

Prince Philip mocked an Army cadet, blinded during a Real IRA bomb attack, by poking fun at his dress sense.

As the Queen asked Stephen Menary how much he could see Philip said: "Not a lot, judging by that tie."

Stephen was wearing the uniform of the Middlesex Cadet Force, which includes a red, blue and yellow tie.

Mr Menary was 14-years-old when he picked up a torch bomb that was thrown at Territorial Army barracks in west London, by the Real IRA in 2001.

He was blinded and lost part of his left arm.

The comment, made by the Duke of Edinburgh during a tree-planting ceremony in Hyde Park, London seven years ago, was revealed by Stephen's mum Carol.

She said: "Prince Philip is completely out of touch with reality, he is from another world. After he said it there was just stunned silence.

"The Queen looked like she wanted to plant Philip next to the tree. She just looked at him open mouthed. I don't think she could believe what he had said.

"I think there was no malice behind it, it was a tactless thing to say.

"Mocking the sight of a blind boy is something, even by his standards. He is a strange man with a very strange sense of humour."

Mr Menary said "I don't think there's any malice in what he says."

A history of verbal gaffes

In his time the Duke of Edinburgh has described the Chinese as " slitty-eyed", and the Hungarians as " pot-bellied".

In 1969 the duke was said to have annoyed Tom Jones after the Royal Variety Performance by asking: "What do you gargle with, pebbles?" He added the following day: "It is very difficult at all to see how it is possible to become immensely valuable by singing what I think are the most hideous songs."

At a WWF meeting in 1986 (he was international president), he said: "If it has got four legs and it's not a chair... the Cantonese will eat it."

In 1995, he asked a Scottish driving instructor: "How do you keep the natives off the booze long enough to pass the test?"

After the Dunblane massacre in 1996 he declared a member of a shooting club was no more potentially dangerous than a cricketer, and also wondered why the unemployed cannot make up their mind whether they want more leisure time or not.

He also upset residents of Lockerbie when on a visit to the town in 1993, he said to a man who lived in a road where 11 people had been killed by wreckage from the Pan Am jumbo jet: "People usually say that after a fire it is water damage that is the worst. We are still trying to dry out Windsor Castle."

On a visit to China in 1986 he told British students: "If you stay here much longer you'll all be slitty-eyed."

In 1999, he angered deaf people with a comment about a Caribbean music band. During a visit to the Welsh Assembly, the Duke met a group from the British Deaf Association, pointed to the musicians, and said: "Deaf? If you are near there, no wonder you are deaf."

In 2002 he asked an Australian Aborigine if he was "Still throwing spears?"
