Britain's Queen Elizabeth, the Queen Mother, leaves the King Edward VII Hospital in central London, to return to Clarence House ahead of the celebrations to mark her101st birthday. * She was admitted to the clinic after she complained of extreme tiredness during the recent heatwave. After a diagnosis that she was suffering from anaemia, doctors administered a blood transfusion. She is expected to make her traditional birthday appearance outside Clarence House.
