Ezra Sihite, Rizky Amelia & Natasia Christy Wahyuni – Lawmakers, including some from the ruling Democratic Party, welcomed the antigraft agency's offer on Tuesday to enlist graft suspect Angelina Sondakh as a justice collaborator to track down others implicated in her case.

In the proposed deal, Democratic lawmaker Angelina would share information with prosecutors in exchange for as-yet undefined leniency, said Corruption Eradication Commission (KPK)deputy chairman Zulkarnain.

"The KPK is clearly convinced that Angelina is not the mastermind of the corruption case related to the athletes' village or corruption cases at the Education and Culture Ministry," said Martin Hutabarat, a member of House of Representatives Commission III, which oversees legal affairs.

The Great Indonesia Movement Party (Gerindra) lawmaker said the offer showed that the KPK believed there were other bribe-recipients on the House Budget Committee, of which Angelina was formerly a member, or House Commission X, which oversees youth and sports affairs.

Deputy House Speaker Pramono Anung welcomed the offer, saying the KPK should use whatever strategy it saw fit to eradicate corruption.

"It is up to them, not to us. The KPK knows better than anyone, including myself," the Indonesian Democratic Party of Struggle (PDI-P) official said. "How Abraham Samad wants to untangle the web is for him to decide," he said, referring to the chairman of the KPK.

He said achieving results was vital, as reports of corruption continued and cases seemed to be getting increasingly sophisticated. He noted that when people with political influence were implicated, the law appeared ineffective.

Democratic Party secretary general Saan Mustopa said the party would support Angelina if she decided to accept the deal.

"Even without the offer to act as a whistleblower, she certainly would have helped to solve the case. There is nothing she would cover up, as this is a part of the commitment by all to unravel the truth," Saan said.

He asked that the KPK be transparent in the investigation. "The Democrats will have no problem with it if it is to uncover the truth," Saan added.

On Tuesday, the KPK allowed Angelina to receive medical treatment for a sinus infection, KPK spokesman Johan Budi said, adding that she was due to return to detention later in the day.

He said the KPK had not received a demand for a stay of detention from Angelina's lawyer, who had previously said her rematernal responsibilities meant she should be released.
