The Madlanga Commission faces renewed scrutiny after the brutal killing of a key witness — and the Democratic Alliance demands urgent protection for all whistleblowers.
What happened
On 5 December 2025, former police officer and private‑security operator Marius van der Merwe — known in the commission as “Witness D” — was assassinated just moments after arriving home with his wife.
The DA has condemned the killing in the strongest terms, calling it a “cold‑blooded assassination” and an attack on the foundation of justice in South Africa.
According to the DA, the murder is not only an attack on one man and his family — but a direct assault on state accountability, democracy, and the rule of law.
They argue the killing was meant to intimidate anyone who might testify or blow the whistle on corruption and wrongdoing.
DA demands urgent protection for whistleblowers
The DA is calling for:
- Immediate protection for all current and future witnesses linked to the Madlanga Commission.
- A full overhaul of laws and systems around whistle‑blower protection.
- A thorough investigation to bring the perpetrators to justice.
In the DA’s view, failing to safeguard those who expose corruption threatens to destroy public trust in the justice system.
Why this matters
- This assassination marks one of the most brazen attacks yet on a witness tied to a national corruption inquiry.
- It raises serious questions about the effectiveness of witness‑protection mechanisms in South Africa — and whether whistleblowers can safely come forward.
- If whistleblowers fear for their lives, many may stay silent — undermining efforts to root out corruption and organised crime.
What now
The DA says it will continue pressing in Parliament for a stronger witness‑protection framework.
Meanwhile, civil society, opposition parties, and the public will likely intensify calls for accountability, justice, and reforms to ensure truth‑tellers are safeguarded.
