Cleric Anjem Choudary has been charged with inviting support for terror group Islamic State.
The charge relates to IS’s status as a “proscribed terrorist organisation”, meaning supporting it is banned in Britain.
Charged alongside the Muslim campaigner is Mohammed Mizanur Rahman.
A statement from Crown Prosecution Service said the charges relate to the two men’s activities between 29 June 2014 and 6 March this year.
Choudary, 48, of Hampton Road, Ilford in east London, was due to appear at Westminster Magistrates’ Court at 2pm on Wednesday.
Sue Hemming, Head of Special Crime and Counter Terrorism at the CPS, said: “Following an investigation by the Metropolitan Police’s Counter Terrorism Command, we have today authorised charges against Anjem Choudary and Mohammed Mizanur Rahman.
“We have concluded that there is sufficient evidence and it is in the public interest to prosecute Anjem Choudary and Mohammed Rahman for inviting support for ISIL (IS), a proscribed terrorist organisation, between 29 June 2014 and 6 March this year.
