In 2006, the AU decided to create a Committee "to consider the implementation of a rotation system between the regions" in relation to the presidency. Controversy arose at the 2006 summit when Sudan announced its candidacy for the AU's chairmanship, as a representative of the East African region. Several member states refused to support Sudan because of tensions over Darfur (see also below). Sudan ultimately withdrew its candidacy and President Denis Sassou-Nguesso of the Republic of the Congo was elected to a one-year term. At the January 2007 summit, Sassou-Nguesso was replaced by President John Agyekum Kufuor of Ghana, despite another attempt by Sudan to gain the chair. 2007 was the 50th anniversary of Ghana's independence, a symbolic moment for the country to hold the chair of the AU—and to host the mid-year summit at which the proposed Union Government was also discussed. In January 2008, President Jakaya Kikwete of Tanzania took over as chair, representing the East African region and thus apparently ending Sudan's attempt to become chair—at least till the rotation returns to East Africa. The current chair is Egypt.
