Jo Swinson, English politician
Joanne Kate Swinson (born 5 February 1980) is a former British Liberal Democrat politician who was Leader of the Liberal Democrats from 22 July to 13 December 2019. She was the first woman and the youngest person to hold the position, as well as the holder of the post for the shortest period of time. Swinson was the Member of Parliament (MP) for East Dunbartonshire from 2005 to 2015 and 2017 to 2019. In September 2020 Swinson became Director of Partners for a New Economy (P4NE).Swinson studied at the London School of Economics, and briefly worked in public relations, before being elected to the House of Commons, becoming the youngest MP at the time. She was a Liberal Democrat Spokesperson covering various portfolios, including Scotland, Women and Equalities, Communities and Local Government, and Foreign and Commonwealth Affairs.In 2010, after the Liberal Democrats entered into a coalition government with the Conservative Party, Swinson was a Parliamentary Private Secretary to Deputy Prime Minister Nick Clegg, and was later appointed Parliamentary Under Secretary of State for Employment Relations and Postal Affairs. She lost her seat in the 2015 election, but regained it in the snap election held two years later. Shortly after returning to Parliament, she was elected unopposed as Deputy Leader of the Liberal Democrats. In July 2019, following the retirement of Vince Cable, Swinson defeated Ed Davey in a leadership election to become Leader of the Liberal Democrats.

Swinson led her party through the 2019 general election shortly afterwards, suggesting she could lead a Liberal Democrat majority government which would revoke Article 50 and cancel Brexit. Instead, Swinson and the Liberal Democrats sustained a net loss in seats, including her own to the Scottish National Party and was disqualified from continuing as party leader. At less than five months, her tenure as leader was the shortest in the Liberal Democrats' history. She is also the only incumbent Liberal Democrat leader to have lost a Parliamentary seat.
