DAP veteran Lim Kit Siang has called for the Parliament to refer former prime minister Najib Abdul Razak for alleged tampering of the National Audit Department's 1MDB report before it was tabled to the last sitting of the house.

This is after auditor-general Madinah Mohamad issued a statement saying that Najib and others had instructed for parts of the report to be deleted or revised 2016.

"This is a most shocking disclosure and a total abuse of power which attacks the very basis of parliamentary integrity and which must viewed most seriously by all Malaysians, in particular MPs.

"If it is established that Najib had tampered with the former auditor-general’s audit report on 1MDB, then it is up to the Committee of Privileges to recommend to Parliament what punitive measure should be meted out to Najib," Lim said in a speech yesterday.

Besides Najib, others named in Madinah's statement include former 1MDB president Arul Kanda Kandasamy, former auditor-general Ambrin Buang, former chief secretary to the government Ali Hamsa, and Najib's former private secretary Shukry Salleh.

Parts of the audit report that were allegedly tampered include those on 1MDB's 2014 financial statement and Jho Low's attendance in a 1MDB board of directors meeting.

Parliament's Public Accounts Committee is probing the alleged tampering, as are the MACC.
