However, it did not specify the allegations or name the site that published the allegation.

A check, however, showed that Sabahkini2.com had carried allegations against the national oil company and implicated a former Umno division leader in a posting yesterday.

A report carried in Sabahkini2.com alleged that a firm linked to the politician had received preferential treatment from Petronas.

It said the former Umno division leader was an independent non-executive chairman of the firm.

“With reference to malicious allegations contained in a post in an unverified online site, Petronas wishes to state in the strongest terms that the allegations are unsubstantiated and untrue.

“Petronas maintains the highest standards of corporate governance and transparency in all our business dealings and we will not hesitate to take action against anyone who continues to malign the reputation and integrity of the company or its people.

“Petronas has filed reports with the relevant authorities in regard to the posting and we leave the matter to the authorities for their further action,” it said in a statement today.
