South Africa will hold its fifth democratic elections in 2014 and the ruling ANC will, in effect, be in the dock.
Barack Obama has led the tributes to Nelson Mandela saying that South Africa's democracy is his 'cherished legacy.'
Rivals of Jacob Zuma looked to capitalise after the South African leader snubbed a ceremony marking the death of 34 miners by police fire.
South African President Jacob Zuma "benefited unduly" from a 208 million rand (£13.8 million) state-funded security upgrade to his private home that included a swimming pool, cattle enclosure and amphitheatre, the public protector ruled today.
In a damning report released six weeks before an election, South Africa's top anti-corruption watchdog accused Zuma of conduct "inconsistent with his office" and said he should repay a reasonable part of the cost of the unnecessary renovations.
"The President tacitly accepted the implementation of all measures at his residence and has unduly benefitted from the enormous capital investment in the non-security installations at his private residence," Public Protector Thuli Madonsela said in her report.
Video posted online appears to show the man accused of 'faking' sign language during Nelson Mandela's memorial 'interpreting' for South African president Jacob Zuma last year.
The footage, apparently filmed in January 2012 at the ANC party's 100th anniversary, shows the man making gestures as Zuma sings to the crowd.
ANC communications manager Keith Khoza told NBC News that the interpreter had translated for party events in the past, but said that the man only “volunteered” and was not paid.
President Zuma announces that the Union Buildings amphitheatre, where Nelson Mandela was inaugurated in 1994, will now be called the 'Nelson Mandela Amphitheatre'.
He said this is a "fitting tribute to a man who transformed the Union Buildings from a symbol of racism and repression to one of peace, unity democracy and progress".
President Zuma jokes that "many leaders, some of whom are present here, have experienced his sharp tongue".
President Jacob Zuma is describing the moment the world first saw a "tall, imposing figure walking out into a world he had left behind 27 years before".
He says South Africans were, at that time, a "downtrodden people" and that they "needed a leader like Madiba".
Zuma refers to Mandela repeatedly as a "freedom fighter".
Daybreak correspondent Richard Gaisford reports that President Zuma is being booed by the crowd.
