The Democratic Alliance has called for urgent parliamentary hearings after the Public Investment Corporation suspended its chief executive and acting chief investment officer amid a growing governance crisis.

The Democratic Alliance (DA) has called for urgent parliamentary intervention following the precautionary suspension of Public Investment Corporation (PIC) chief executive Patrick Dlamini and acting chief investment officer August van Heerden, warning that South Africans' pension savings could be placed at risk if governance concerns are not addressed.

The PIC board confirmed on Monday that Dlamini had been placed on precautionary suspension in line with the corporation's whistleblower policy while allegations of impropriety against him are investigated.

The board stressed that the suspension does not amount to a finding of wrongdoing and is intended to ensure a fair, objective and independent investigation.

"The suspension does not, in any way, constitute a finding nor is it a pronouncement of any wrongdoing on the part of the CEO," the PIC said in a statement.
