Margaret Thatcher is one of the most iconic politicians of the twentieth century. With the possible exception of Winston Churchill, no other Prime Minister has had such an impact on modern British history. Like it or not, her radical social and economic policies have made Britain the country it is today. Without Margaret Thatcher there could have been no New Labour, no Tony Blair and no David Cameron. Now Robin Harris, for many years Thatcher's speechwriter, trusted adviser and the draftsman of two volumes of her autobiography, has written the defining book about this indomitable woman. He tells her extraordinary life story, from humble beginnings above her father's grocer's shop in Grantham, her early days as one of the first women in Westminster who became known as 'Thatcher milk-snatcher' during her days in the Ministry for Education and then as Prime Minister. We follow her through the 'Winter of Discontent', the tribulations of the miners' strike and the Falklands War. And Harris writes a stunning account of her exit from power and tells of her life after number 10.
