Chad went to the polls on Monday in the first round of its presidential election with incumbent Idriss Déby Itno virtually assured of extending his 21-year rule after his main rivals boycotted the vote. Key opposition leaders have withdrawn from the vote after claiming that his Patriotic Salvation Movement (MPS) party stole February parliamentary elections and the start of Monday's vote was marred by hitches. Opposition leaders Saleh Kebzabo, Wadal Abdelkader Kamougue and Ngarlejy Yorongar say they will not recognise the poll amid demands for reforms including the issuing of new voters' cards.
