The DA won two Western Cape by-elections, gaining ground as the ANC declines.

The Democratic Alliance (DA) won two by-elections in the Western Cape, narrowly defeating the ANC in Cederberg and Langeberg, while the ANC retained a ward in Gauteng. The DA gained ground in Graafwater and Bonnievale, with the PA making significant advances but falling short of victory. The ANC's decline in the Western Cape and its internal strife in Johannesburg, including allegations of vote rigging, signal shifting political dynamics. Cape Town Mayor Geordin Hill-Lewis is now seriously considering running for DA leadership following John Steenhuisen’s decision not to seek re-election.
