Margaret Thatcher was Prime Minister of the United Kingdom from 1979 to 1990 and Leader of the Conservative Party from 1975 to 1990. She was the first female British prime minister and the longest-serving British prime minister of the 20th century. A polarising figure in British politics, Thatcher is nonetheless viewed favourably in historical rankings and public opinion of British prime ministers. Her tenure constituted a realignment towards neoliberal policies in Britain, with the complicated legacy attributed to Thatcherism debated into the 21st century.
