Margaret Thatcher : Volume One: The Grocer’s Daughter Paperback / softback

'A fascinating account... Campbell's research is as exhaustive as it is meticulous' ObserverWhen Margaret Thatcher unexpectedly emerged to challenge Edward Heath for the Conservative Party leadership in 1975, the public knew her only as the archetypal Home Counties Tory Lady, more famous for her hats than for any outstanding talent: she had a rich businessman husband, sent her children to the most expensive private schools and sat in Parliament for Finchley.

Yet almost overnight she reinvented herself. Journalists who set out to discover where she came from were amazed to find that she had grown up above a grocer's shop in Grantham.

Within weeks of her becoming Tory leader an entirely new image was in place, based around the now famous corner shop beside the Great North Road; the strict Methodist upbringing; and her father, who taught her the 'Victorian values' which were the foundations of her subsequent career. In the first volume of the first full-scale biography of Margaret Thatcher since her fall from power - and the first thoroughly to explore her early life - John Campbell re-examines the mythology and suggests a more complex reality behind the idealised picture accepted by Lady Thatcher's early biographers.

He portrays an ambitious and determined woman ruthlessly distancing herself from her roots, until the moment in 1975 when they suddenly became a political asset.
