Radical London preacher Anjem Choudary, who previously called for gay people to be stoned to death, has been jailed for five years on terror charges after allegedly encouraging support for ISIS.

The hardline Islamic preacher is the former UK head of the Islamist group al-Muhajiroun or Islam4UK, which was banned in the UK in 2010.

He suggested at a press conference in 2009 that gay people should be stoned to death, and has maintained that stance since.

Choudary, who frequently causes controversy with his extremist views and high-profile protests, had faced charges under terrorism laws for calling on social media for people to support ISIS.

He was charged alongside Mohammed Rahman, 32, of Whitechapel, east London, with one offence under section 12 of the Terrorism Act 2000, which bans people from “inviting support for a proscribed organisation”.

Today, Mr Choudary was jailed for five and a half years after backing the group in an oath of allegiance published online.

Justice Holroyde sentenced him during the trial at the Old Bailey.

The preacher is known for his extreme anti-gay views.

He claimed in a Fox News interview last year that he thought those found guilty of “sodomy”, where there are four witnesses, should be stoned to death under Sharia law, which he said should be implemented worldwide.
