Malaysian Anti-Corruption Commission (MACC) chief commissioner Abu Kassim Mohamed is to be replaced soon and his replacement is believed to be a senior officer from the Attorney-General's Chambers.

Sources familiar with the matter suggest that Abu Kassim could have been allegedly pressured by the Prime Minister's Office to vacate his post. He will step down on Aug 1.

However, in a statement issued later, MACC denied there was any pressure on Abu Kassim.
