LEGISLATORS have increased pressure on the head of the Nigerian lower house of parliament and his deputy to resign following their indictment by a corruption probe panel. Umar Ghali Na’Abba and his deputy, Chibudom Nwuche, should immediately step aside or resign their positions to allow an investigation into various allegations of corruption levelled at them, one legislator said. The group of legislators threatened to lodge formal complaints with the police and the anti-graft agency if the officers failed to resign within 48 hours. – AFP
