Imam Suliman Gani has denied allegations he supports the terror group and said he was surprised to hear Cameron's criticism of him.
Following on from allegations made by BBC reporter Andrew Neil, Cameron first told the House of Commons on April 20 that Gani "supports IS [Daesh]."
Cameron then again took to parliament on Wednesday to try and draw a link with Gani, an imam from Tooting in south London, and the opposition Labour party's London Mayoral candidate Sadiq Khan, who is a Muslim and who also comes from Tooting.
Corbyn raises the issue of the PM critiquing Sadiq Khan for sharing platform with Suliman Gani — PM does not repeat the "supports IS" line

Cameron is *still* pushing the line about Suliman Gani, even though its now ON THE RECORD his own members invited him to events. Unreal

In questioning Labour leader Jeremy Corbyn, Cameron said: "The honorable member for Islington might be interested in this. He [Gani] describes women as subservient to men, he said that homosexuality was an unnatural act.
"He stood on a platform with people who wanted an Islamic state. That is why his [Corbyn's] attempts to deal with anti-Semitism are utterly condemned to failure, because he won't even condemn people who sit on platforms with people like that."
Imam Slams 'Preposterous' Claims
However, the exchange soon became embarrassing for Cameron after Corbyn reminded the prime minister that Gani was in fact a Conservative party supporter, while it was also revealed the imam had been previously invited to a Conservative party event encouraging Muslims to become councilors.
Gani slammed Cameron's comments, describing them as "preposterous."
"I have openly condemned the barbarity and monstrosity of ISIS [Daesh]," he told Sky News, while denying that he had any issues with homosexuality.
"I have no problem with any person's personal inclination."

The imam said he was "very surprised" to be the target of an attack by the prime minister, given his links with the Conservative party.
"I was invited to a Conservative Muslim forum, encouraging Muslims to become councilors for the Conservative Party. So how is it I am labeled as a person who is supporting IS [Daesh]?
"This is really something I cannot accept. I demand a serious, immediate apology."
Cameron has since defended his comments against Trump, who drew international criticism after calling for a "total and complete shutdown of Muslims entering the United States" in December following the San Bernardino terror attacks.
