Islamist preacher Anjem Choudary has pleaded not guilty to two terror offences relating to banned organisation Al-Muhajiroun (ALM).
The 57-year-old, of Ilford, east London, is accused of being a member of a proscribed organisation and addressing meetings to encourage support for that same proscribed organisation.
He appeared at the Old Bailey via video link from HMP Full Sutton for a hearing on Monday, where he denied the two charges.
Choudary was arrested in east London on July 17 last year, while a second suspect, Khaled Hussein, was detained at Heathrow having arrived on a flight the same day.
Hussein, 29, of Canada, also appeared at the Old Bailey via video link from HMP Wormwood Scrubs and pleaded not guilty to membership of ALM.
Both men have been remanded in custody and are due to stand trial at Kingston crown court from June 4, in a case that is predicted to last between six and eight weeks.
An earlier hearing was told Choudary had addressed meetings of the Islamic Thinkers Society, which prosecutors said is ALM “for all intents and purposes”.
Choudary and Hussein are both due to attend a further hearing in their case at the Old Bailey on April 23, to be overseen by Mr Justice Wall.
Proscription is the banning of an organisation based on an assessment that it commits or participates in, prepares for, promotes or encourages, or is otherwise concerned in terrorism, according to the Home Office.
