British Prime Minister David Cameron and President Jacob Zuma have agreed that Libyan leader Muammar Gaddafi must go. Cameron, who is on a working visit to South Africa, told reporters in Pretoria on Monday that he and Zuma believed Gaddafi needed to step down from power. However, Zuma said: 'What happens to Gaddafi must be decided by the Libyan people. You need to negotiate how, why and where he must go.'
