Nigeria: Court defers ruling on presidential vote

Nigeria's Supreme Court on Thursday deferred ruling on a challenge to President Umaru Yar'Adua's April 2007 election victory, but did not set a date for handing down its final judgement. Former military ruler Muhammadu Buhari and former vice president Atiku Abubakar, Yar'Adua's main challengers in last year's polls, have appealed to the Supreme Court to annul his victory in an election deemed flawed by foreign and local observers.
