Excerpt:
Anjem Choudary, the leader of the banned extremist group al-Muhajiroun, which has inspired a number of Britons to join Isis, is set to be released from prison this week.
Choudary is one of about a dozen jailed radicals who are due out in the coming months, sparking concerns about the demands this will place on the police and the security services.
Choudary has served half of a five and-a-half year prison sentence handed down in 2016 for "inviting support of a terror group" and is now entitled to automatic parole.
The Observer has been told that, in anticipation of his release, pencilled in for this Wednesday, he is being moved from Frankland prison in County Durham to Belmarsh high security jail in London.
