Jakarta. Investigators at the Corruption Eradication Commission, or KPK, will summon newly reappointed speaker of the House of Representatives Setya Novanto on Tuesday (13/12) as a witness over the notorious e-KTP corruption case.

"KPK has sent a summon letter for Setya Novanto, the speaker at the House of Representatives, related to the e-KTP case," KPK spokesman Febri Diansyah said.

He would not comment on potential lines of questioning, but said Setya's name had been mentioned by graft convict and former treasurer of the Democrat Party Nazaruddin, who said the e-KTP project had been controlled by Setya and former Democrat Party chairman Anas Urbaningrum.

The e-KTP case emerged after the House of Representatives' Commission II, which oversees home affairs and elections, approved the Home Affairs Ministry’s budget proposal for procurement of the electronic ID card, or e-KTP, program which cost the state Rp 6.7 trillion ($500 million).

The project, initially planned to provide biometric ID cards to all Indonesians aged 17 and older, was mothballed in Oct. 2015 following a series of problems, including a late start, technical glitches and officials demanding payments from residents to provide the ostensibly free service.

The case has caused approximately Rp 2.3 trillion in state losses.

The House, at the end of November, reappointed Setya as speaker, reinstating him despite a major scandal last year when he was accused of trying to extort billion dollars worth of shares from the local arm of US mining giant Freeport McMoran.

Setya resigned as speaker in December after an inquiry was launched over the extortion allegation.
