At least 50 world leaders, including Barack Obama, David Cameron and the president of Iran, will join global stars such as Bono, Oprah Winfrey and the Spice Girls at an extraordinary four-hour memorial service to honour Nelson Mandela in Johannesburg on Tuesday.
One of the biggest gatherings of heads of state, religious leaders and celebrities the world has ever seen will take place in a 95,000-seater football stadium in the township of Soweto.
President Obama is likely to deliver an address at the event, while some of the globally-renowned pop stars attending may also perform, although the programme remains a closely-guarded secret.
"Rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add 'within the limits of the law' because law is often but the tyrant's will, and always so when it violates the rights of the individual." Thomas Jefferson
"If people can’t trust not only the executive branch but also don’t trust Congress, and don’t trust federal judges, to make sure that we’re abiding by the Constitution with due process and rule of law, then we’re going to have some problems here." - Barack Obama, June 7, 2013
