Reputation

Margaret Thatcher was not merely the first woman and the longest-serving Prime Minister of modern times, but the most admired, most hated, most idolised and most vilified public figure of the second half of the twentieth century. To some she was the saviour of her country who created a vigorous enterprise economy which twenty years later was still outperforming the more regulated economies of the Continent. To others, she was a narrow ideologue whose hard-faced policies legitimised greed, deliberately increased inequality and destroyed the nation's sense of solidarity and civic pride. There is no reconciling these views: yet both are true.

Biographer John Campbell (2011b, p. 499)

Thatcher's tenure of 11 years and 209 days as British prime minister was the longest since Lord Salisbury in the late 19th century (13 years and 252 days, in three spells) and the longest continuous period in office since Lord Liverpool in the early 19th century (14 years and 305 days).

Having led the Conservative Party to victory in three consecutive general elections, twice in a landslide, she ranks among the most popular party leaders in British history regarding votes cast for the winning party; over 40 million ballots were cast in total for the party under her leadership. Her electoral successes were dubbed a "historic hat trick " by the British press in 1987.

Thatcher ranked highest among living persons in the 2002 BBC poll 100 Greatest Britons. In 1999, Time deemed Thatcher one of the 100 most important people of the 20th century. In 2015 she topped a poll by Scottish Widows, a major financial services company, as the most influential woman of the past 200 years; and in 2016 topped BBC Radio 4 's Woman's Hour Power List of women judged to have had the biggest impact on female lives over the past 70 years. In 2020, Time magazine included Thatcher's name on its list of 100 Women of the Year. She was chosen as the Woman of the Year in 1982 when the Falklands War began under her command, resulting in the British victory.

In contrast to her relatively poor average approval rating as prime minister, Thatcher has since ranked highly in retrospective opinion polling and, according to YouGov, is "see in overall positive terms" by the British public. Just after her death in 2013, according to a poll by The Guardian, about half of the public viewed her positively while one third viewed her negatively. In a 2019 opinion poll by YouGov, most Britons rated her as Britain's greatest post-war leader (with Churchill coming second). According to the poll, more than four in ten Britons (44%) think that Thatcher was a "good" or "great" prime minister, compared to 29% who think she was a "poor" or "terrible" one. She was voted the fourth-greatest British prime minister of the 20th century in a 2011 poll of 139 academics organised by MORI. In a 2016 University of Leeds survey of 82 academics specialising in post-1945 British history and politics, she was voted the second-greatest British prime minister after the Second World War.
