Britain's first and only female prime minister Baroness Thatcher has died at the age of 87 after suffering a stroke. Lady Thatcher's children Mark and Carol said their mother, who suffered bouts of ill health in recent years, died peacefully on Monday morning. Downing Street, which joined Buckingham Palace in flying its flags at half mast, said the politician would be given a full ceremonial funeral with honours at St Paul's Cathedral. Sky sources understand she died at the Ritz in central London where she had been staying since January following a minor operation.
