Princess Charlene of Monaco will host a two-week training camp for South Africa's swimming team in the build-up to the London Olympics. As Charlene Wittstock, the princess swam for South Africa in the 4x100 metres medley at the 2000 Sydney Olympics, where her team finished fifth. South Africa said its squad would go to Monaco from July 7-22 in the final leg of preparations before heading to the Games.
