Johannesburg - The embattled Estate Agency Affairs Board (EAAB) has been placed under administration, Human Settlements Minister Tokyo Sexwale said on Tuesday."I am compelled in the interests of bringing certainty and order to place (the board) under administration," Sexwale said in Johannesburg.He also called for the Special Investigating Unit to probe the EAAB."I've also decided the Special Investigating Unit must step in. They must bring in a very strong broom to clean up this mess."Sexwale was addressing estate agents, after his department took over the EAAB in May. It previously fell under the authority of the department of trade and industry.The EAAB has had three acting CEOs since Nomonde Mapetla was fired early last year.The board's chairperson, Ina Wilken, resigned this month shortly after taking up the position. Before her, acting CEO Bryan Chaplog was removed by the board. The board said this was part of a rotation of the position.Last year, chairperson Thami Bolani was suspended by Trade and Industry Minister Rob Davies.Sexwale dissolved the board, saying it was dysfunctional."To date when a board is supposed to be having 15 members, they are left with three."Sexwale will hold a summit with estate agents in September.
