Religiously conservative Adhaalath Party (AP) leader Sheikh Imran Abdulla has petitioned the country's apex court to review his jailing over a terrorism conviction.
Imran was sentenced to 12 years in prison for inciting violence during a major opposition protest held in May 2015. Prosecutors had blamed the violence and destruction of property on a speech delivered by Imran during the protest.
The Supreme Court had earlier rejected Imran's final appeal.
AP deputy leader Ali Zahir in a Tweet said the top court has now been asked to review its decision to reject Imran's final appeal.
"Freeing jailed joint opposition leaders remains pivotal to the opposition alliance's transitional efforts," Zahir added.
Imran becomes the latest jailed opposition figure to seek release in the wake of the opposition alliance's stunning victory in last month's presidential elections.
The High Court earlier this month has freed jailed former president Maumoon Abdul Gayoom before overturning the bribery conviction of Jumhoory Party (JP) leader Gasim Ibrahim on Monday.
The remaining opposition leader and former president Mohamed Nasheed meanwhile is set to return to the Maldives from self-imposed exile on November 1.
Nasheed however is yet to petition the top court to review its decision to uphold his terrorism conviction.
