Malaysian Anti-Corruption Commission (MACC) chief Abu Kassim Mohamed said he has no plans to quit for now as he wants to see through the commission's investigations.

Abu Kassim was responding to rumours that he will be forced out of office over the commission's high-profile probe into the RM2.6 billion deposited into Prime Minister Najib Abdul Razak's personal bank accounts and SRC International.

"There is no pressure on me nor will I quit because of pressure because this responsibility is important.

"I must complete them, particularly the ongoing investigations," he told MACC.fm in an interview.

Abu Kassim added that his possible departure from MACC was a subjective matter.

"Today, I have not made any application or request to quit or require but that may happen in future, I do not know.

"But as long as I am healthy, I will continue to lead the MACC until a time when my health does not permit or when I need a rest," he said.

However, Abu Kassim said that day has yet to come and he will continue on as the MACC chief for now.

Last Friday, former premier Dr Mahathir Mohamad ( photo ) had expressed concern that Abu Kassim may be forced to retire prematurely on health grounds.

He likened this to how then attorney-general Abdul Gani Patail was removed from office in July last year.

"The removal of Abu Kassim will only convince the people that all that is being said against the government is true - that it exists merely to prevent the rule of law (from) being applied to the leadership of the nation," said Mahathir.

In the interview with MACC.fm , Abu Kassim also addressed attorney-general Mohamed Apandi Ali's move to return the commission's investigation papers into the SRC International and RM2.6 billion case.

"Many appear confused that this is unusual when investigation papers are returned but actually, it is only unusual when they are not returned," he said.

Abu Kassim said this was normal practice when the Attorney-General's Chambers wants to seek further clarification.

He added that the MACC will address the issues raised by the chambers over the investigation papers soon but did not elaborate on what they were.
