The DA has its eye on ensuring that it has the largest share of the vote in Gauteng, with the party saying the ANC is at "its weakest" thus far in the province. 

With 26 days to go until the 2019 general election, the DA's head of campaigning, Jonathan Moakes, said trends showed that the ANC had never been weaker in Gauteng.

"The ANC is in serious trouble and the DA is on the ascent," he said. 

Business Day understands that according to some polling, ANC support was between 47% and 50% in Gauteng two weeks ago, but had recently dropped below this. The DA's support in the past three weeks in Gauteng is said to have apparently grown between six and seven percentage points.

The DA has vowed to bring the ANC below 50% in the country's economic hub. If this happens it is likely that the province will be governed by a coalition government.

On Wednesday, EFF leader Julius Malema said his party was open to working with any party, including the DA and the ANC. However, he said the EFF"s working relationship with the DA was strained. 

The EFF had voted with the DA-led coalition in Johannesburg and Tshwane following the 2016 local government elections, handing over the reins of the metros to the DA.  

DA national spokesperson Solly Malatsi said the party was not conducting background talks on coalitions, but was focused on its campaign.

"We going into this election with maximising out performance and making sure our contribution to this elections it to get the largest share of the vote in Gauteng," he said. "We are in it to win it."

Malatsi said any coalition talks, if need be, would only happen after elections. 

The DA it was also confident about the strides it had made in the Northern Cape, another province in which the party hopes to bring the ANC below 50%. 

In the Western Cape, Moakes said the DA was likely to retain its majority. He said the party was at the same level it was four weeks before the 2014 elections.

In 2014, the DA won the Western Cape with 59.38%.

Despite this, the DA was not taking anything for granted, Moakes said.
