Parliament's chief financial officer Leslie Mondo has been dismissed with immediate effect following the findings of a disciplinary hearing, the national legislature said on Friday.

Mondo was found guilty on four out of five counts of misconduct.

The charges relate to the salary advance of R186,000 paid to National Assembly Secretary Zingile Dingani for a security wall around his plush Panorama residence.

Mondo had allegedly ordered Parliament's finance department to grant Dingani the advance payment.

"Mr Mondo was charged with five counts of misconduct related to financial matters. He was found guilty on four of these," Parliament said in a statement.

Mondo has already been informed of the findings.

"No further internal processes will be entered into."

The disciplinary hearing against Dingani had not yet been concluded. Both Dingani and Mondo were placed on special leave in March after the misconduct allegations surfaced.

The Auditor General was asked to investigate, and later recommended that Parliament discipline them.
