Sheikh Rachid Ghannouchi

Should the world fear the rise of political Islam in the newly democratic Middle East? The Arab Spring has thrust the ideas and ideology of one man into the centre of this crucial question. Before the revolutions began, Sheikh Rachid Gannouchi lived in Hemel Hempstead and was one of the world's leading Islamist ideologues, urging the Muslim Brotherhood to accommodate modate the ideas of secularism, democracy and acceptance of equal political rights for non-Muslims. But after the region begun to rise up against dictators, he has become even more powerful and his ideas have been tested as never before. He returned to his native Tunisia in 2011 and is now spiritual leader of Tunisia's largest political party, but his influence extends far beyond North Africa. As the Muslim Brotherhood and its ideological brethren try and find a place in a democratic world, his controversial ideas have won acolytes in the Arab World, Turkey and South East Asia.
