"Margaret Thatcher, who led conservative resurgence in Britain, dies at 87 NBC World News — Former British Prime Minister Margaret Thatcher, the ""Iron Lady"" who led a conservative resurgence in her home country and forged a legendary partnership with President Ronald Reagan, died Monday following a stroke, her spokesman said. She was 87. Thatcher led Britain from 1979 to 1990 and was the longest-serving prime minister of the postwar era. The spokesman, Lord Tim 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."" Thatcher's daughter said in 2008 that she had been suffering from dementia for eight years, and had to be reminded that her husband was dead. She had a well-known friendship with Reagan during his two terms as president in the 1980s. They shared an allegiance to free-market principles and opposition to the Soviet Union."
