ANC Chief Whip Mdumiseni Ntuli has defended the National Assembly Speaker Thoko Didiza who is facing harsh criticism over refusal to subpoena Paul O’Sullivan and Brown Mogotsi.

Ntuli called the latest criticism labeling it as unfair attacks and unjustified and misdirected.
In a virtual interview on SABC News, ANC Chief Whip Mdumiseni Ntuli defended National Assembly Speaker Thoko Didiza against criticism for declining to issue subpoenas for forensic investigator Paul O’Sullivan and businessman Brown Mogotsi to appear before Parliament’s Ad Hoc Committee.
Ntuli described the attacks on Didiza as unjustified and misdirected, insisting she is ensuring proper procedure is followed.
Ntuli, a member of the committee probing misconduct and infiltration in the criminal justice system, said Didiza wants decisions safeguarded from court challenges.
He explained that the committee must address security concerns raised by O’Sullivan (currently in the UK with death threats) and Mogotsi (demanding funded protection) before forcing in-person appearances.
O’Sullivan left the country with his seven kids.
He rejected claims of undue delay, noting correspondence with the Speaker began late last year, with responses from O’Sullivan in December and January.
Ntuli stressed unanimity on holding O’Sullivan accountable for alleged contempt toward Parliament, while warning that bypassing process could embarrass the committee legally.
The ANC maintains Didiza’s guidance protects the inquiry’s integrity.
The committee continues its work toward the mid-February deadline, with Ntuli calling for responsibility rather than shifting blame to the Speaker.
