Richmond Park is a parliamentary constituency in the House of Commons of the United Kingdom. Sarah Olney of the Liberal Democrats won the seat at a by-election in 2016 after Zac Goldsmith of the Conservative Party stood down in protest over expansion of Heathrow Airport. Goldsmith stood as an independent at the by-election, but the Conservative nomination was restored to him for the 2017 general election, at which he regained the seat with a slim majority. Olney won the seat from Goldsmith a second time at the 2019 general election.
