Hani al-Sibai, an al-Qaeda cleric suspected of radicalising “Jihadi John”, lives in a £1 million house leafy street in fashionable west London.

He is said to be one of the “key influencers” of the Islamic fanatics believed to have recruited and trained gunman Seifeddine Rezgui.

Egyptian-born al-Sibai, 54, reportedly lives on £50,000 a year in handouts, disability living allowance, with his wife and five children.

Asked how he could justify taking so much in benefits, al-Sibai, who is under investigation suspected of benefit fraud, told the Daily Mail: “Ask David Cameron, don’t ask me.”
