North Wiltshire MP James Gray says he is concerned that BNP chairman Mike Howson is a youth leader for youngsters at Rudloe Air Cadet unit.

Mr Howson sparked controversy last month when he set up BNP patrols in Corsham in a bid to combat anti social behaviour.

He claims the vigilante patrols were a response to concern by Corsham residents about thugs in the town.

But Mr Gray says that any member of a youth organisation responsible for young people should not hold a political position.

He said: "Members of the armed forces can be court marshalled for being publicly linked to a political role so I don't see why this should be any different.

"I think it is very questionable that he should be taking part in political activities at the same time as leading youngsters.

"The ATC should be equally concerned that someone like this can be allowed to lead in this organisation.

"What if a black child was to join, would he treat them any differently from the other cadets and how would that affect the child."

Mr Howson, who was commended as youth worker of the year in 2006, after his cadets nominated him, hit back saying that Mr Gray has forfeited his right to judge others after his 19-month affair with countryside campaigner Philippa Mayo.

Mr Howson said: "I will speaking to the adulterer at his next surgery about his comments.

"I don't think he is really in a position to attack the BNP. He may not like our policies but we don't approve of adultery.

"As far as I am concerned my political life and my youth work stay totally separate.

"When I am at the air cadets I am there for the youngsters and not to encourage future voters."

Air Training Corps headquarters said that if the welfare of cadets and staff at a Squadron was brought into doubt because of Mr Howson's political activities an investigation would be launched.

A spokesman said: "The Air Cadet organisation encourages diversity and does not tolerate improper behaviour, which includes actual or encouragement of racism."
