Followers of jailed hate preacher Anjem Choudary are still posting videos promoting violent Islamic extremism online. Scores of videos by Choudary's acolytes were available through Google and YouTube searches, the Times reported.

Choudary, 48, was found guilty of terrorism offences after leading a series of radical Islamic organisations in Britain, and appearing on news programmes advocating extremism while carefully treading the line to avoid stepping over into criminality.

He encouraged support for Islamic State (Isis) in a series of talks posted on YouTube, and said that he recognised that caliphate had been established after IS (Daesh) chief Abu Bakr al-Baghdadi announced the formation of IS in June, 2014, the Old Bailey heard.

Last month Choudary, 49, and co-defendant Mohammed Mizanur Rahman, 33, were found guilty of inviting support for IS between 29 June 2014 and 6 March 2015.

Several of the videos being shared feature acolyte Siddhartha Dar, who travelled to Syria and allegedly took part in IS mass execution films, shooting at least one person in the head. In one video he describes Jews as corrupt and arrogant, and says Adolf Hitler acted to stop a Jewish conspiracy for world domination.

After reporting restrictions on Choudary's conviction were lifted, counter-terrorism expert Andrew Silke told Sky News: "There will be a spike in interest in what he said and material he's produced.

"It will get a lot of viewings. A lot of people will see it for the first time now and obviously the fear is some of those people will be influenced by what they read and what they see."
