Nigerian opponents of military rule today threatened civil disobedience, strikes and rallies to remove the dictator, General Sani Abacha, and thwart his so-called transformation into a civilian president. The opposition National Democratic Coalition, which supports the claim of the detained Moshood Abiola to the presidency, yesterday told Nigerians to prepare for strikes and rallies to prevent Abacha from gaining the presidency. Another opposition group, the United Action for Democracy, has told people to boycott Saturday’s National Assembly elections, now likely to be the only elections contested for representation on a national level.
