DA leader John Steenhuisen is said to have committed a series of blunders which resulted in the loss of confidence by party heavyweights as well as its funders, insiders have said.
Sowetans sister newspaper Sunday Times understands that the decision by Steenhuisen to not stand for re-election came about after several talks with his inner circle.
The inner circle includes public works minister Dean McPherson, Cape Town mayor Geordin Hill-Lewis, and home affairs minister Leon Schreiber.
