LONDON - Former British Prime Minister Margaret Thatcher, whose conservative ideas made an enduring impact on Britain, has died. She was 87.

Her former spokesman says Thatcher died this morning of a stroke.
Prime Minister David Cameron also expressed sadness, saying "we have lost a great leader, a great prime minister and a great Briton."
Buckingham Palace says Queen Elizabeth II was also sad to hear the news of the death of Margaret Thatcher.
The palace said Monday that the queen will be sending a private message of sympathy to the family.
Thatcher, the country's first female prime minister, re-made Britain's economic landscape after coming into office in 1979 with a free-market philosophy and the goal of privatizing state industries. And she would wage some hard-nosed battles with the country's labor unions.
Her influence was felt long after she left office in 1990. Tony Blair, whose Labor Party languished in opposition as the Conservative Thatcher held power for more than a decade, ended up adopting many of her views.
Thatcher's forceful personality and hard-driving style earned her the nickname of the "Iron Lady." It was a term that was reinforced when she led Britain into war against Argentina in 1982 after the Argentines invaded the Falkland Islands. She forced them to retreat.
In 1984, she escaped a brush with terrorism. An I-R-A bomb exploded in a hotel hosting the annual conference of the Conservative Party. It narrowly missed Thatcher, but killed five others.
The badly-divided Conservatives eventually pushed her from power in 1990, and the party has struggled since then to regain its footing.
In her later years, she grew frail after a series of small strokes, and gave up most public speaking on the advice of her doctors.
UK: Thatcher to receive ceremonial funeral
The British government says former Prime Minister Margaret Thatcher will receive a ceremonial funeral with military honors.
Thatcher -- known as the "Iron Lady" -- died Monday from a stroke at 87. Prime Minister David Cameron cut short a trip to Spain and France upon hearing the news.
Downing Street says Queen Elizabeth II has authorized a ceremonial funeral -- a step short of a state funeral -- to be held at St. Paul's Cathedral.
It says the funeral will be attended by a "wide and diverse range of people," and the service will be followed by a private cremation.
It did not provide further details on the timing of the service, saying only that the arrangement are "in line with the wishes" of Thatcher's family.
