The family of jailed Malaysian opposition leader Anwar Ibrahim say they have sought a royal pardon over his conviction for sodomy.
Anwar was jailed for five years earlier this month in a case which he has always maintained was brought to keep him out of politics.
He has widely been seen as the only real threat to the ruling coalition.
His family said he was a political prisoner who had been "tyrannised" and that his health was at risk in prison.
"The court may have pronounced a guilty verdict but our father is innocent," Anwar's daughter, Nurul Nuha Anwar, said in a statement on behalf of the family. The statement said the conviction had been a miscarriage of justice.
"We placed our confidence in the constitutional process and believe that justice will prevail when all the facts are scrutinised without political intervention."
Sodomy is illegal in Muslim-majority Malaysia, though very few people are ever prosecuted.
Anwar - who has already served one six-year term for another sodomy conviction that was later overturned - has always insisted he is innocent.
In a statement released after he was sent to jail on 10 February, he said the charge was "complete fabrication - coming from a political conspiracy to stop my political career" and that he would be silenced.
The petition for a pardon was submitted to the Yang di-Pertuan Agong, Malaysia's elected monarch. The monarchy rotates between the hereditary rulers of nine Malaysian states.
