The Malaysian Anti-Corruption Commission (MACC) is not investigating the corruption case involving AirAsia and jet engine manufacturer Rolls-Royce PLC, Minister in the Prime Minister's Department Paul Low said.

"As of now, there is no statement that can link any party to any offence under the MACC Act 2009 regarding the case probed by (UK's) Serious Fraud Office (SFO)," Low said in a parliamentary written reply today.

However, he said, the MACC welcomes any information on this case that any individual can furnish.

Low also said the MACC had cooperated with the SFO.

On Jan 21, it was reported that the SFO had named AirAsia Group as one of several foreign parties involved in bribery cases with jet engine manufacturer Rolls-Royce PLC.

The bribery in the AirAsia deal was one of 12 charges brought against Rolls-Royce after a four-year investigation into its dealings with clients in Indonesia, Thailand, India, Russia, China and Malaysia.

Low was responding to a query from Wong Chen (PKR-Kelana Jaya, photo) on whether any action had been taken against the AirAsia executive involved in the scandal.

In a statement issued after this Wong said the minister's response showed that the government was either "clueless, negligent or has no real intention of eradicating corruption".

According to the statement of facts filed with the Crown Court at Southwark in London, Rolls-Royce failed to prevent its employees from providing an AirAsia Group executive with credits worth US$3.2 million (RM14.2 million) for the maintenance of a private jet.

AirAsia Group subsidiary AirAsia X - which has had dealings with Rolls Royce - had denied allegations it sought personal favours or gratification from the engine manufacturer.

'Transaction went through due process'

AirAsia X said the transaction involving the jet had gone through the "due approval process" and received approval from its audit committee and board of directors.

It was also recommended to its shareholders for approval during its general meetings in 2014, 2015 and 2016, and was also disclosed in AirAsia X's initial public offering prospectus prior to the meetings.

AirAsia X was listed on July 10, 2013.

The UK documents state that On July 8, 2013, three contractual documents were signed between Rolls-Royce and AirAsia X, including the Supplemental Financial Assistance Agreement, which made reference to the US$3.2 million of credits.

However, none of the documents mentioned that the credits would be used for the private jet.

It said by late November 2013, the credits were transferred by the AirAsia X senior employee to the company, which was the vehicle through which the AirAsia Group executive and other private individuals owned the jet.

The document said the credits for the private jet used by the AirAsia group executive was solicited through an AirAsia X senior employee in 2011.

It also alleged that there was an attempt to conceal the fact that the credits, given to AirAsia X in 2013, would be used for the the private jet, which was unrelated to the AirAsia Group.

The document did not name who the AirAsia Group executive was.

In June last year, AirAsia Bhd reportedly purchased a Bombardier BD-700-1A10 Global Express, which had been used by AirAsia Bhd executive chairperson Kamarudin Meranun and group chief executive officer Tony Fernandes, since 2012.

The private jet was purchased from Caterhamjet Global Ltd (CJG), a company in which Kamaruddin and Fernandes held a 18.56 percent indirect stake and which is also a member of the Tune Group.
