The family of jailed Malaysian opposition leader Anwar Ibrahim has sought a royal pardon in a last-ditch effort to try free him from a sodomy conviction.

Anwar, 67, began a five-year prison sentence Feb. 10 after Malaysia's top court turned down his final appeal, ruling there was overwhelming evidence that he sodomized a former male aide.

Nurul Nuha Anwar, his second daughter, said in a statement late Monday that there has been a "miscarriage of justice" against her father, whom she described as a "political prisoner".

She said the family believes "justice will prevail when all the facts are scrutinized without political intervention."

The case was widely seen as politically motivated to eliminate threats to the ruling coalition, whose popularity has been eroding in the last two elections.
