Thatcher provides an accessible and scholarly introduction to the personality and career of Britain's first female political leader and the twentieth century's longest serving Prime Minister. Providing a balanced narrative and assessment of one of the most significant figures of the post-war era, this new biography examines the reasons why Margaret Thatcher has been admired by many as an architect of national revival, yet loathed by others as the author of widening social and geographical division. It will be essential reading for all students of twentieth-century history and politics.
