Mohamed Ghannouchi ( "Muhammad Al-Ghannushi"; born 18 August 1941) is a Tunisian politician who was Prime Minister of Tunisia from 1999 to 2011. Regarded as a technocrat, Ghannouchi was a long-standing figure in the Tunisian government under President Zine El Abidine Ben Ali. He also served as the Acting President of Tunisia from 14 January 2011 to 15 January 2011, holding the powers and duties of the office nominally for the absent President Zine El Abidine Ben Ali, who had fled the country due to the 2011 revolution. On 15 January 2011 the presidency was declared vacant by the Constitutional Court and Ben Ali's term was officially terminated, leading to Speaker of Parliament Fouad Mebazaa taking office as Acting President. Ghannouchi stayed on as Prime Minister for six more weeks after Ben Ali's overthrow before himself resigning.
