Dr Tamimi, director of the London-based Institute of Islamic Political Thought and campaigner for ken Livingston, Has previously praised suicide bombers and even said he would volunteer personally for a suicide mission in the Middle East. In a BBC interview in 2004 he said: "If I can go to Palestine and sacrifice myself I would do it. Why not? Sacrificing myself for Palestine is a noble cause. It is the straight way to pleasing my God and I would do it if I had the opportunity."
In 2006 he was the main speaker at a London conference which had the backing of Mr Livingstone and was held the day before the anniversary of the July 7 terror attacks. It was Dr Tamimi who invited the radical Islamic preacher Yusuf al-Qaradawi to speak at a conference in London in 2004. Al-Qaradawi, who has defended suicide bombers and the persecution of homosexuals, was welcomed to City Hall and embraced by Mr Livingstone.
