President Vaclav Klaus has been released from hospital, and is back on holiday with his wife Livia at the presidential chateau in Lany, outside Prague. Mr Klaus was admitted to Prague's General Teaching Hospital on Thursday evening after apparently overexerting himself in the hot weather. He was released on Friday after undergoing tests. The 62-year-old president checked himself into hospital after falling ill following a game of tennis. Mr Klaus had spent last week at a spa in Karlovy Vary, where he was recovering from a recent bout of tonsillitis. A spokesman for the president said tests had shown Mr Klaus was completely healthy.
