Prime Minister Najib Razak has been urged to declassify the auditor-general’s report on 1MDB after whistleblower website Sarawak Report leaked what it claims to be parts of the document.

"Sarawak Report provided Malaysians with the best Hari Raya present, by exposing the discoveries by the auditor-general on 1MDB which has been covered up by the Najib administration via the Official Secrets Act (OSA)," said Petaling Jaya Utara MP Tony Pua in a statement last night.

"In the spirit of honesty and decency during the month of Aidil Fitri celebrations, Najib Razak must immediately instruct the declassification of the auditor-general’s report, which was never meant to be permanently classified (under the Official Secrets Act, OSA).

"After all, if he has nothing to hide and insists that Sarawak Report has once again falsified and doctored documents, in this case the auditor-general’s report, then making public the 'real' report will once and for all destroy Sarawak Report’s credibility," said Pua.

He said failure to declassify the auditor-general’s report however only increases public suspicion about what he claimed could be "the biggest cover up in the history of the world".

He said the website, operated by sister-in-law to former British prime minister Gordon Brown, Clare Rewcastle Brown, achieved a feat he, as Public Accounts Committee (PAC) member, could not.

"It is a feat even I could not achieve because the PAC chairperson Hasan Arifin has ruled that even PAC members could not retain a copy of the document.

"This is despite the fact that we have been specifically cleared to access the report.

"I could only read the report during the PAC meetings or upon request at the parliamentary office," said Pua.

'More damning than PAC'

He said the leak, if genuine, offers the world confirmation of earlier speculations for the reason for classifying the audit under OSA.

"It is because the auditor-general’s comments on the fishy tales and documents supplied by 1MDB are even more damning than the already damning PAC report on the 1MDB investigations," claimed Pua.

Yesterday the website, which has been at the forefront of investigative reports on 1MDB's troubles, claimed it had in possession the classified report.

"Sarawak Report has now gained extensive access to the auditor-general's report on 1MDB, along with key accompanying documents from the enquiry," it said.

The whistleblower site listed out the various concerns that auditor-general Ambrin Buang had pointed out in his report, especially with regard to several questionable fund transfers. Sarawak Report also provided details on these fund transfers.
