Mr Choudary was detained alongside another man, Mohammed Rahman, and on Wednesday both appeared at Westminster magistrates’ court, where they were remanded in custody.
Mr Choudary, 48, and Mr Rahman, 32, have been charged with inviting support for a proscribed terrorist organisation, namely Isis, contrary to section 12 Terrorism Act 2000.
The pair were arrested by members of the Metropolitan Police’s Counter-Terrorism Command on suspicion of being members of a proscribed organisation in September last year, but have remained on bail throughout the Met’s investigation.
