There is no record chief welfare minister Aburizal Bakrie ever contributed to Susilo Bambang Yudhoyono and Jusuf Kalla's 2004 campaign fund, said Indonesian Corruption Watch (ICW) corruption and politics coordinator Adnan Topan Husodo in Jakarta on Thursday.

However, he said the ICW had uncovered a number of irregularities in the fund – which propelled the pair to President and Vice President in the country's first general election – including donors with no addresses, fictitious company names and benefactors who were known not to have been able to have afforded their listed donations.

He said such practices violated Presidential Legislative Law No. 23/2003 Article 45 (1). The General Elections Commission (KPU) has not commented on the finding.

Adnan, accompanied by ICW researcher Abdullah Dahlan, said forcing political parties to publish the names of their benefactors in public financial reports would not guarantee fool-proof transparency.

"The audit by public accountants is not a cleaning process for the parties' campaign funds. They can't easily claim that they are clean," he said.

He called on the KPU to anticipate repeated incidences by preparing stringent guidelines for auditing campaign funds.

Critics have said the KPU is ill-equipped to audit the estimated 20,000 party campaign funds – as demanded by the 2008 Elections Law – as the body only employs 800 registered public accountants.

The 38 political parties are required to submit one financial report for each of their regency, municipal, provincial and central offices. – JP/Ricky Yudhistira
