MACC denies immunity deal with witness in Muhyiddin probe

A Malaysian Anti-Corruption Commission official has firmly denied claims that the agency offered preferential treatment or immunity from prosecution to a principal witness in the case against Muhyiddin Yassin. The statement addresses growing public scrutiny over the conditions under which witnesses provide evidence in high-profile corruption investigations. The MACC's position suggests that all witnesses, regardless of their own legal exposure, are treated according to standard investigative protocols. The commission has historically faced questions about its independence and the consistency of its approach to different cases involving political leaders. Muhyiddin, who served as Prime Minister from 2020 to 2021, has faced multiple legal challenges since leaving office. The witness in question has provided testimony central to allegations against the former leader, prompting debate over whether extraordinary arrangements were necessary to secure cooperation.
