World leaders to gather for Mandela funeral
South Africa is preparing for the arrival of a flood of world leaders for the funeral and memorial services for former president Nelson Mandela.
Among those who have already indicated that they will be travelling to South Africa to honour the anti-apartheid hero, who died at his Johannesburg home at the age of 95 on Thursday night, are US President Barack Obama and his two predecessors, George W Bush and Bill Clinton.
