Margaret Thatcher, the unyielding conservative politician who from 1979 to 1990 served as Britain’s first female prime minister – and the 20th century’s longest running – died Monday. She was 87.
Her spokesman Lord Bell made the announcement: “It is with great sadness that Mark and Carol Thatcher announced that their mother Baroness Thatcher died peacefully following a stroke this morning. A further statement will be made later.”
Buckingham Palace, meanwhile, released a statement of HRH’s intentions. “The Queen was sad to hear the news of the death of Baroness Thatcher,” it read. “Her Majesty will be sending a private message of sympathy to the family.”
