When Public Protector Busi Mkhwebane was recommended by Parliament, the DA was the first to raise concerns about her intelligence background and suspicions she was either a spy or too close to the spies.The Economic Freedom Fighters hit back strongly, saying it would not allow her rejection merely because she was a black woman. Since then much water has passed under the bridge and the party has accepted she is unsuited for the post.In fact Mkhwebane represents danger to that office’s independence. Her latest revelations to MPs that she has hired a chief financial officer seconded from the State Security Agency (SSA) have served to confirm most of the suspicion that has circulated about her since she got into that office.Staff members have long spoken anonymously to the media about the undue influence state security has over the office and its work.What’s even more curious is that she actively solicited the services of the SSA, apparently after not receiving help from Treasury. Mkhwebane said she approached the SSA “knowing there might be additional capacity” that would be useful to her office. She said there was a manager from her office who was being trained by the SSA.All this has blown her cover. Not so long ago she was threatening to sue the DA for the spy allegations. But now it will be much harder for her to draw a distance between the SSA and herself.Before she was appointed, the office of the public protector was renowned for its robustness, fearlessness and independence.Then public protector Thuli Madonsela deserves much of the credit for former president Jacob Zuma finally paying for some of the repairs to his home in Nkandla. She is also responsible for the commission of inquiry into state capture that will start in a few weeks.She was the safeguard of our values and of the Constitution.All that fight and energy disappeared when Mkhwebane came into office. What has since taken place is nothing short of the capture of this most crucial institution. The incumbent is toothless, incompetent and completely out of her depth.The honourable thing would be for her to leave and allow someone else who is interested in implementing its core mandate to help South Africans.
