Margaret Thatcher is one of the most significant political figures of the twentieth century—a Prime Minister whose impact on modern English history is comparable only to Winston Churchill's. Like them or not, her radical policies made Britain the country it is today. And like her or not, Margaret Thatcher's legacy remains a massive political force, responsible for laying the groundwork for New Labour, Tony Blair, and David Cameron, and for England's strong political allegiance to the United States throughout the Cold War.

Now Robin Harris, for many years Mrs. Thatcher's speechwriter, close adviser, and the draftsman of both volumes of her autobiography, has written the definitive book about this indomitable English woman. In this international bestseller, he tells the compelling story of her life, from humble beginnings above her father's grocery store in Grantham, her early days as one of the first women in Westminster (she became known as "Thatcher Milk Snatcher" during her time in the Ministry of Education), and then on to her groundbreaking career as Prime Minister (by which time her reputation already demanded a more powerful epithet: "Iron Lady").

We follow Thatcher through hard-fought political battles and experience with her the tribulations of the English miners' strike and the Falklands War, of her sometimes troubled friendship with Ronald Reagan, and their shared staunch opposition to Communism. We learn of the political intrigue behind the scenes at Ten Downing Street. And how during one of the darkest hours of her premiership she refused to alter course and, adapting the words of an English play, declared to her enemies, inside and outside the Government, "You turn if you want to. The Lady's Not for Turning," summing up for admirers and detractors alike the defiance and consistency of Mrs. Thatcher's approach. Throughout Not for Turning we sense the passionate intellect which fuelled her ambitions, drove her into and out of one of the highest offices in the English-speaking world, and has established a unique political legacy that continues even after her death…

Not for Turning is an unforgettable portrait of Britain's first female Prime Minister, written by one of her most trusted advisers, and a fitting tribute to an extraordinary politician and leader.
