Steenhuisen said individuals should zero in on different things, such as policing, tax collection and water and power arrangements, rather than attempting to split the region away from the remainder of the country.

The mission to isolate the Western Cape from SA acquired energy recently when a non-political development called CapeXit tried to make the area an autonomous country.
The development is trying to get the help of 1.6 million individuals to demand a mandate on whether the Western Cape ought to be isolated from SA.
Last month, the Cape Independence Advocacy Group (CIAG) mentioned a mandate on Cape freedom from Western Cape chief Alan Winde.
The gathering's representative Phil Craig said CIAG chose after "conference with its autonomy accomplices CapeXit, the Cape Independence Party, and the Freedom Front Plus, and following the choice by the DA and AfriForum, to seek after independence for the Western Cape.
"Those on the two sides of the Cape Independence banter should comprehend a mandate on Cape Independence will be the start and not the finish of the cycle," said Craig.
"From political race results distributed by the Electoral Commission we know beyond a shadow of a doubt that most Western Cape citizens have never had the public government they decided in favor of. They can't communicate their serious disappointment with the bearing SA has taken through typical decisions. You can't unelect an administration you never chose in any case.
"The constitution explicitly furnishes an instrument to talk with the Western Cape individuals on exactly the present circumstance, a common mandate called by the head and not by the president. This is majority rules system in real life."
