Margaret Thatcher: Her life and career
Former Prime Minister Baroness Thatcher has died at 87 following a stroke, her spokesman has said.
Lord Bell said: "It is with great sadness that Mark and Carol Thatcher announced that their mother Baroness Thatcher died peacefully following a stroke this morning."
Lady Thatcher was Conservative prime minister from 1979 to 1990.
David Cameron called her a "great Briton" and the Queen spoke of her sadness at the death.
But she often polarised public opinion, particularly following her battle with trade unions.
