Excerpt:
Anjem Choudary has been released from prison after serving half of the five-and-a-half-year sentence he received in 2016 for urging support for Isis and pledging allegiance to the terrorist group.
Choudary, 51, who was a key figure for a succession of extremist Islamist groups, emerged early on Friday morning from Belmarsh prison in south-east London.
Authorities have been making preparations to stop him from inciting support for terrorism and he will in effect be banned from making any public statements or speaking with the media.
Before the release, the prisons minister, Rory Stewart, said Choudary, from Ilford in east London, remained a "genuinely dangerous" figure and that the "completely pernicious" cleric would be watched "very, very carefully" by police and security services.
