The new auditor for 1MDB will be announced soon, said Finance Ministry's Treasury secretary-general Irwan Serigar Abdullah, though he declined to comment on other 1MDB-related questions.

"This is way out of (relevance to the event). I don't want to respond to this, thank you," he said, when quizzed about 1MDB during a press conference at the closing ceremony for the 'Bahasa Inggeris 1Malaysia' programme in Kuala Lumpur today.

When met by reporters after the press conference and asked the same questions related to 1MDB's recent announcement that their 2013 and 2014 financial statements can no longer be relied upon, he merely said: "No comment".

However, when pressed further on when they would announce the new auditor for 1MDB after revealing that their current auditor Deloitte Malaysia would be quitting, he said: "We will announce soon.”

With Deloitte's notice of quitting, this makes it the third audit firm to part ways with 1MDB since its inception in 2009.

Irwan Serigar also heads the new 1MDB board of directors.

On Tuesday, 1MDB had said that its 2013 and 2014 audited financial statements should no longer be relied on until allegations made by the US Department of Justice (DOJ) are determined in court.

This was then repeated by Deloitte, which said that its audit of 1MDB in 2013 and 2014 would have been impacted if it had known at that time the information contained within the DOJ lawsuits.

The DOJ last Wednesday filed two lawsuits to seize more than US$1 billion of assets which it alleged were purchased using funds siphoned from 1MDB.
