Some 500 supporters of jailed former opposition leader Anwar Ibrahim gathered outside the Sungai Buloh Prison last night to celebrate his 69th birthday.

They also came together as part of the ongoing campaign to demand for his freedom, on the 548th day that he had spent behind bars.

A large birthday cake was brought on to the makeshift stage, where Anwar's family members and friends were already gathered, at about 11.30pm.
