Sithole, who had been an ANC councillor from 2016 to 2021, said:
We joined the DA because - as the majority in Ward 17 - we were advised by community members that the DA is the only option as the ANC didn't deliver its promise.
He said they studied the DA's constitution and made the decision.
"Where the DA has been given an opportunity to lead, they tend to lead well. We've seen it in the uMngeni Local Municipality as well as the Western Cape governments," said Sithole.
"As a person who believes that we should put people first, I had to consider a lot of things. But it was the people who were showing the way. That made it easy for me."
