Authorities have had their hands full trying to deal with Ses'khona Peoples Rights Movement members and Economic Freedom Fighters (EFF) supporters.

Officers had to throw stun grenades into a crowd of EFF supporters who clashed with their ANC counterparts.

A group of EFF supporters were contained in an isolated spot in Church Street.

Unlike earlier, police managed to escort a large crowd of Ses'khona supporters to the Grand Parade.

They sang and danced as they made their way down Darling Street to a gathering spot in front of the Cape Town City Hall.
