The case is centred on his alleged remark to an audience that Mr Sukarno had written an earlier version of Pancasila that did not prioritise a belief in God.

JAKARTA: The Indonesian National Police has said that a facial recognition analysis has confirmed that a naked woman who appeared in sex chats allegedly involving Islamic Defenders Front (FPI) leader Rizieq Shihab is female activist Firza Husein.
Hery Cahyono, a face recognition expert from the police's Indonesia Automatic Fingerprints Identification System (Inafis) division, said the authorities used several methods, including biometrics, to check whether the woman who appeared in the sex chats was really Firza.
"This case is fabricated and libellous," Firza's lawyer Azis Yanuar said.
"This case is fabricated and libelous,” Firza’s lawyer Azis Yanuar said.
The issue is watched closely because Mr Rizieq was one of the key organisers of massive street demonstrations to oust outgoing Jakarta governor Basuki Tjahaja Purnama, who is behind bars after being found guilty of blasphemy in the Muslim-majority country.
Mr Hery said police compared pictures of the female activist when she was arrested over an alleged plot against the government on Feb 4 with her suspected pictures in Whats App conversations, which have gone viral.
Earlier this year, the police summoned Firza for questioning after screenshots of what appears to be steamy Whats App chats between Rizieq and Firza were uploaded to the Internet.
Firza, who was a coordinator of the Solidaritas Sahabat Cendana foundation, which is connected to the family of former president Soeharto, was reportedly having a relationship with the married man.
