The Anti-Corruption Agency (ACA) will quiz PKR de facto leader Anwar Ibrahim over the Lingam video scandal.

Anwar, who exposed the video on Sept 19, will meet ACA investigating officers at his office in Petaling Jaya Friday afternoon.

The video , which cast aspersions on the credibility of the judiciary, showed senior lawyer VK Lingam having a telephone conversation with purportedly Chief Justice Ahmad Fairuz Sheikh Abdul Halim.

The duo were discussing the appointments of 'friendly' senior judges in the eight-minute edited clip, said to be recorded in 2002 when Ahmad Fairuz was Chief Judge of Malaya.

Following this, PKR vice-president R Sivarasa and Anwar's aide Sim Tze Tzin were called in by the ACA to have their statements recorded.

It is understood that the individuals implicated in the video have yet to be called in for questioning.

Source will not be revealed

Meanwhile, Sivarasa said PKR was cooperating with the ACA in order for the agency to carry out its duties.

"I told them before that they are not going to get anything new from Anwar. But they said that since I mentioned his name, they needed to interview him as a formality," he said when contacted today.

Sivarasa, who is a lawyer by training, believes that the ACA would ask Anwar to divulge the source of the video.

ACA officers had asked Sivarasa and Sim to do the same during their respective interviews.

"It's unnecessary. They should just authenticate the video and look into the issues arising from the content," said Sivarasa, stressing that PKR is not prepared to divulge the source.

The government has appointed a three-member panel to look into the authenticity of the tape.

The panel is headed by former Chief Judge of Malaya Haidar Mohd Noor. The other two members are former Court of Appeal judge Mahadev Shankar and social activist Lee Lam Thye.

About a week after the clip emerged, Ahmad Fairuz issued a denial via de facto law minister Mohd Nazri Abdul Aziz. The latter said that it was not him at the end of the line.
