Nurfika Osman – The country's top antigraft body said on Wednesday that it had no intention of probing the explosive allegations in reports published by two Australian newspapers based on US diplomatic correspondence released by WikiLeaks.

"We are not going to investigate them and we do not have any plan to do so in the future," said Johan Budi, spokesman for the Corruption Eradication Commission, or KPK. Johan declined to elaborate on the reasons for the decision.

Adnan Topan Husodo, deputy chairman of watchdog Indonesian Corruption Watch, said the KPK could not investigate the claims because it would be very difficult for the commission to do so.

"The information in the cables is only statements made by several people who are concerned about a particular nation and it is hard to confirm that information," Adnan said.

"The government must first show us whether the claims are true or not," he said. He said the ICW had urged the government to clarify the allegations in reports published by The Age and Sydney Morning Herald.

The cables allegedly included a note from the US Embassy in Jakarta that stated it had doubts about the integrity of President Susilo Bambang Yudhoyono. Ani Yudhoyono, the first lady, was accused of enriching herself through her position.

"Our government, through the Foreign Affairs Ministry, has called the US ambassador to clarify the claims and the president wrote a response published one day after the report in the Australian newspapers," Adnan said.

He added that he suspected the government would now remain silent regarding the leaked diplomatic cables. "Now it is up to the public to interpret the issue as a whole," he said. "If the president remains silent, the public will become suspicious and think that there's truth behind the claims."

Adnan said that Indonesian officials were not the type of people to resign elegantly, like leaders in Japan, if they did something wrong.

An outspoken activist group, Petisi 28, on Monday called on the KPK to look into the information contained in the Australian newspaper reports. Haris Rusli Moti, chairman of Petisi 28, said he was upset the KPK would not be investigating the claims.

"We are disappointed," Haris said. "It is weird, since we were welcomed by the KPK's report receiving division on Monday.

"This is an important issue and I hope the KPK considers it a serious matter," Haris continued. However, he said he was pleased the group had at least drawn attention to the matter.

"I knew from the first day we went to the KPK that the chance was small, but at least we did something," he said.
