Helen Zille the leader of the official opposition, Democratic Alliance will on Wednesday step down as Cape Town mayor. She will be gazetted as a member of the Western Cape provincial legislature. The DA won a clear majority in the province in last week's elections, assuring Zille of the premier's post.

“As soon as the IEC (Independent Electoral Commission) puts her name in the gazette as a member of the provincial government she'll cease to be mayor because you can't be a councillor and an MPP (member of provincial parliament) at the same time," spokesperson Robert MacDonald said.
In a related development DA chief executive officer, Ryan Coetzee, said the DA's growth of more than 1 million votes (1 014 628) nationally had seen it increase in size by about 35 percent.
“The DA has achieved all three of its key objectives in this election campaign: to keep the ANC below a two-thirds majority, to win an outright majority in the Western Cape, and to significantly strengthen our position as the official opposition in South Africa."
He said it had never been "inevitable" that the party would do as well as it had. Like the ANC, the DA had had to contend with the emergence of "a significant new opposition party" in the shape of COPE, to compete for votes with almost every other opposition party and to mount a nationwide challenge to the ANC.
The DA's federal executive is to meet Tuesday. Coetzee said it would discuss plans for the local government elections in 2011, when it aimed to win cities and municipalities across the country to build a platform from which to launch a campaign for national government in 2014.
