Featuring on journalist Zenzele Ndebele’s breakfast show, Chamisa said he regretted the way Bulawayo deputy mayor Tinashe Kambarami and Dube exchanged words.
“It is totally unacceptable, it was not called for,” said Chamisa.
He said councillors must follow processes to investigate corruption.
Chamisa also hit out at local government minister July Moyo for interfering with council business.
Chamisa said Moyo should not send an investigation team to investigate his councillors but let the Bulawayo be the arbiters.
