English Defence League founder Stephen Lennon has denied assaulting a police officer during clashes with Islamic protesters.
Lennon, 27, of Layham Drive, Luton, was arrested by police in Kensington, west London, as the nation stopped to mark the anniversary of Armistice Day.
Five others associated with his group were also arrested, as members of Muslims Against Crusades, a group which purports to "expose the enemies of Islam", burned remembrance poppies.
Two Muslim protesters were arrested for public order offences.
One officer was taken to hospital with a head injury during the clashes, as about 50 men linked to the EDL were kept separate as they shouted abuse.
Lennon pleaded not guilty to a charge of assaulting a police officer during a brief hearing at West London Magistrates' Court.
He was granted unconditional bail and a trial date was set of January 12.
About 30 supporters gathered outside the court, some bearing EDL placards.
