Nelson Mandela 'steady improvement' in hospital 3 April 2013 Last updated at 11:18 Former South African President Nelson Mandela is making "steady improvement" under treatment for pneumonia, his doctors have said. South Africa's presidency said in a statement that Mr Mandela had been visited by his family as he continues to make progress. He was responding well to treatment and was much better than when admitted to hospital on 27 March, it said. The hospital stay is Mr Mandela's fourth in just over two years. In December he was treated for a lung infection and gallstones - his longest period in hospital since leaving prison in 1990. Last week the former president, 94, had fluid drained from his lungs at the hospital, the name of which has not been disclosed. There are no details yet on how much longer he will stay there.
