Former Czech president Václav Havel, who has been in hospital for 11 days, was able to breathe without a respirator on Thursday as his condition improved. A spokesperson for Prague’s Motol hospital said that Mr Havel’s health was, however, still a cause for concern. The former president was admitted to hospital with breathing difficulties over a week ago, where he underwent minor surgery. The operation was followed by complications and Mr Havel has spent the last 11 days in intensive care. Mr Havel suffers from chronic bronchitis and had part of his right lung removed in 1996 after being diagnosed with cancer.
