In secretly recorded footage in the northern town of Keighley, BNP leader Nick Griffin -- who recently hosted French National Front leader Jean-Marie Le Pen -- rails against the Koran and acknowledges his views are legally dangerous.
"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," he says at one point.
He tells his audience they should stand up for the party or "they (Muslims) will do for someone in your family. "I will get seven years if I said that outside," he adds.
Other footage in "The Secret Agent" shows one BNP member expressing a wish to blow up mosques with a rocket launcher and to machine-gun worshippers with "about a million bullets." Another member tells how he put dog faeces through an Asian shop's letterbox, while a third describes how he beat up a Muslim man. "I'm kicking away ... it was fantastic," he says.
Yna mae'r twat Griffin yn mynd ymlaen i ddeud fod o'n "victim of selective editing" - pel petai'r BBC wedi torri'r clips ohono fo yn mynd rownd yn bwydo bwnis bach pinc fflyffi yn ei ardd. Y c*nt iddo fo.
Pam fod pobl yn fotio i gociau wyn fel yma? Yr unig reswm ellai feddwl achos fod nhwythau hefyd yn fasdads hiliol aflan eu hunain. Sgym pur.
