“The arrest is what our party wants,” said Saan Mustopa, the party’s deputy secretary general. “All party members, from the beginning, really expected him to be arrested immediately.”

But political observers and analysts have a different take on the arrest of the country’s most-wanted graft fugitive: This, they say, is going to be the true test for the ruling party and the president.

From his hiding place, the 32-year-old lawmaker and former Democratic Party treasurer spent the past two months launching damning attacks against officials of both the party and the Corruption Eradication Commission (KPK).

Nazaruddin has accused Democratic chairman Anas Urbaningrum of graft worth billions of rupiah (hundreds of thousands of dollars). Also, he accused Youth and Sports Affairs Minister Andi Mallarangeng and Democratic lawmaker Angelina Sondakh of complicity in the Southeast Asian Games athletes village graft scandal — the same one he is a suspect for.

He has also accused at least three KPK officials of unethical behavior and colluding with Democratic officials to spare Anas from any investigation.

And he has claimed he has evidence to prove his allegations. In a video interview over Skype broadcast on television, Nazaruddin showed the supposed proof: a flash drive, a compact disc and a document bearing Anas’s signature.

In the wake of all this, separate surveys in the past month have shown damage inflicted to the reputations of both President Susilo Bambang Yudhoyono and the KPK.

Politicians, analysts and activists interviewed by the Jakarta Globe on Monday all agreed that with Nazaruddin’s return, light should be shed on the allegations.
