US President Barack Obama and his two predecessors, George W Bush and Bill Clinton have said they will be travelling to South Africa to honour Nelson Mandela.
The three will travel together on the Air Force One presidential plane, accompanied by their wives. Mr Obama has also invited the other two living former presidents, Jimmy Carter and George HW Bush.
The office of George HW Bush said he will not be able to travel due to his health.
Nelson Mandela's first ever television interview was given to ITN reporter Brian Widlake in May 1961.
Former ITV News presenter Sir Trevor McDonald was the first journalist to interview Nelson Mandela after his release from prison in 1990.
Nelson Mandela was a towering figure of utter integrity who will be remembered as the greatest African.
