Zille has faced considerable opposition and confrontation from the ANC. In September 2006, the provincial ANC MEC Richard Dyantyi announced that he planned to replace the city's mayoral system with an executive committee. The move would have resulted in reduced mayoral power, and the governing party would not itself have been able to assign the ten seats on the committee, which would instead have been allocated on a proportional representation basis. Dyanti and Zille agreed to retain the current mayoral system if the ANC were provided with two additional sub-committees in areas of the city controlled by the ANC. The matter was thus resolved.
