BNP activists exposed on camera.

ACTIVISTS in the British National Party confess to committing racially-motivated crimes -- including an attack on an Asian man -- in an undercover documentary to be broadcast tonight.

The film shows BNP leader Nick Griffin condemning Islam as a ``vicious wicked faith'' -- and claiming that he would face seven years in prison if he made the comments in public.

A BBC reporter who spent six months undercover with the BNP recorded another of the far right group's members, Steve Barkham, confessing to taking part in a racially-motivated attack on an Asian man during the 2001 Bradford riots.

Another BNP member, Stewart Williams, tells reporter Jason Gwynne that he wants to ``blow up'' Bradford's mosques with a rocket launcher and to machine-gun worship pers with ``about a million bullets''.

Mr Griffin says in footage which was recorded secretly at a meeting in Keighley, which was called to discuss a spate of child sex attacks: ``You've got to stand up and do something for the British National Party because otherwise they (Muslims) will do for someone in your family. That is the truth. For saying that, I tell you, I will get seven years if I said that outside, if I said that in front of people who go and report it to the police. ''

He tells his audience that the Koran encourages followers to ``take any woman you want as long as they're not Muslim women'', again adding that expressing such views in public would land him in jail.

Mr Griffin goes on: ``That's the way that this wicked, vicious faith has expanded through a handful of cranky lunatics about 1, 300 years ago until it's now sweeping country after country. ''

The BBC reporter was helped to infiltrate the BNP's West Yorkshire branch by former local BNP organiser Andy Sykes, who became a mole for anti-fascist group Searchlight two years ago. Programme producer Karen Wightman said the BBC had put security measures in place to protect Mr Sykes and Mr Gwynne from reprisals by BNP members.

Material from the documentary would be handed to police and the Crown Prosecution Service, she said, adding: ``We hope that police forces will investigate and that charges will be made. ''

Searchlight's director of research Nick Lowles said: ``The BNP want to be judged as a respectable political party.

``It's a party which says it's changed and clearly it hasn't.

``There is a layer of BNP support who wouldn't consider themselves overtly racist and would actually be shocked by the anti-Semitism, by the laughing about the racism, by the laughing about the violence. ''

In more secretly-recorded footage, Mr Barkham gives a graphic description of what he says was his role in assaulting an Asian man during the 2001 Bradford riots.

On camera, Mr Barkham tells the BBC reporter: ``I gave him a good f hiding, because that's what he asked for.

p SECRET Agent is to be broadcast on BBC1 tonight at 9pm. A West Yorkshire Police spokeswoman said: ``We will be investigating the claims made to identify what, if any, offences may have taken place.
