Watch as ANC officials officially launch the centennial celebrations in honour of the late president Nelson Mandela.
Sunday, 11 February marks 28 years since Nelson Mandela was released after serving 27 years in prison.
ANC president Cyril Ramaphosa, who attended a sermon at the St George's Cathedral on Sunday morning, is still on course to speak at 15:00 at the launch of the celebrations at the Grand Parade in Cape Town.
This is the same time Mandela addressed the country following his release from prison in 1990.
Ramaphosa did not answer journalists' questions regarding what the future holds for President Jacob Zuma after the service.
Pressure is mounting on the ruling party to make an announcement on Zuma's fate.
