Regular updates on South Africa's biggest philanthropic event of the year, the annual CEOSleepout. A maximum of 200 CEOs and their specially invited guests will brave the sub-zero temperatures of Johannesburg's winter, exposed to the elements in the same way as homeless people do every night. To celebrate the 100th anniversary of the month of Nelson Mandela's birth, this year's CEOSleepout is being held at Liliesleaf Farm in Rivonia, Johannesburg on 11 July. Liliesleaf is South Africa's iconic heritage site where Mandela and other heroes of The Struggle regularly met to plot to downfall of apartheid.
