South Africa's new president Cyril Ramaphosa calls for end to 'negativity'

South African President Cyril Ramaphosa has given his first state of the nation address, saying it is time for South Africans to put discord behind them.

Mr Ramaphosa delivered a message of optimism and renewal after a dramatic week in which he was elected by ruling party lawmakers following the resignation of predecessor Jacob Zuma, whose tenure was marked by corruption scandals.
