The family of jailed former opposition leader Anwar Ibrahim held a special prayer sesssion tonight as the judicial review for the PKR defacto chief's Sodomy II conviction looms tomorrow.

The gathering was attended by about 150, family, friends and supporters started at 6.30pm and ended at 11pm at the former opposition's leader's residence in Segambut.

Speaking to those present, Anwar's eldest Nurul Izzah Anwar said that while tomorrow's review is the final legal recourse for her father, this does not mean the end of their efforts to free him.

She said a variety of methods will be used to achieve their final objective which will be announced soon.

Among others, she said that they will file more international and online petitions, urging all to sign them as it will be sent to the Agong who as specified under Article 42 of the constitution has the power to release anyone.

She claims that as the rule of law has been abandoned in her father's case, they have to turn to other means.

Nurul urge all supporters to assemble outside the Federal Court in Putrajaya as a sign of solidarity with her father tomorrow morning.

Tomorrow the Federal Court will hear Anwar's judicial review application against his Sodomy II conviction from accusations leveled against him by his ex-assistant Saiful Bukhari Azlan.

He is seeking for the court to invoke Rule 137 of the Rules of the Federal Court 1995 and review his earlier case based on merit.

Anwar, 68, is currently serving his sentence at the Sungai Buloh Prison after the Federal Court affirmed his earlier conviction by the Court of Appeal on Mar 7 2014.
