The leader of the far-right British National Party (BNP) has been arrested.
Mr Nick Griffin was held on suspicion of incitement to commit racial hatred after an undercover TV documentary on racism in the organisation.
It also emerged today the founding chairman of the party was arrested on Sunday. Mr John Tyndall (70) of Brighton was arrested on suspicion of incitement to commit racial hatred following a speech he made in Burnley, Lancashire, in March, a BNP spokesperson said.
Parts of the speech were covertly filmed and shown in the BBC programme Secret Agent. His arrest by West Yorkshire Police was the 10th made in connection with the documentary, which featured footage showing BNP activists confessing to race-hate crimes and Mr Griffin condemning Islam as a "vicious, wicked faith".
Mr Tyndall, a former chairman of the National Front, was released on police bail pending further inquiries yesterday.
A BNP spokesperson said: "The BNP condemns this arrest because the party is committed to freedom of speech, though that doesn't mean that the party necessarily approves of the words for which Mr Tyndall has been arrested.
"Whatever differences the party leadership may have with Mr Tyndall, everyone wishes him well with regard to this case."
