Police have again summoned opposition aligned Jumhoory Party (JP) leader Gasim Ibrahim for questioning.
The business tycoon who was questioned by police last week have again been summoned on Sunday at 4pm, his lawyer said.
The Maamigili lawmaker told reporters later that police had questioned him over a recent speech he had given during a JP rally where he was alleged to have hinted at possible bribing of fellow lawmakers.
Gasim during his speech had vowed to assist re-election of lawmakers if they voted in favour of ousting parliament speaker Abdulla Maseeh.
Gasim is the latest top opposition figure to have faced a possible backlash after the failed bid to unseat the speaker on Monday.
Police had questioned the now government lawmaker Dhangethi MP Ilham Ahmed after JP lawmaker Abdulla Riyaz and later main opposition Maldivian Democratic Party (MDP) secretary general Anas Abdul Sattar.
Amid the chaos in parliament on Monday, the government had comfortably defeated the motion.
