Journalist Margaret Gilmore has told talkRADIO Anjem Choudary's ability to inspire terrorism was aided by the rise of the internet, and he will be cut off from this key resource when he enters prison.
The radical preacher was convicted of one count of helping inspire terrorism on behalf of Isis. He faces a period of up to 10 years in prison once he is sentenced in September.
The father of five posted videos and speeches up onto YouTube, and police today revealed he has connections to 500 jihadists working for the terrorist caliphate.
Gilmore, who is also a senior research fellow at the Royal United Services Institute for Defence and Security Studies (RUSI), explained how the conviction and upcoming sentencing will hamstring Choudary.
"He won't be allowed to go online and it certainly dimishes his ability," she explained. "It's the big increase in online activity which has helped him - to establish links with Belgian extremists, for instance.
"The authorities have come to realise these people are dangerous when they're preaching.
"The rise of the internet, the power to put words and speeches online and inspire and target particularly vulnerable young people, this has made a difference.
"He [Choudary] is a man with the gift of the gab, trained as a lawyer. He is different to most other people, he was inspiring. The police needed hard evidence to convict him."
