Sarah Olney of the Liberal Democrats won a significant victory in Richmond Park, overturning a large Conservative majority. The win was attributed to a backlash against Brexit, with the community expressing opposition to a hard Brexit and leaving the single market. Zac Goldsmith, who resigned over Heathrow expansion, faced a humiliating defeat. His controversial mayoral campaign was also a factor. The election results were closely watched, with Olney's win seen as a verdict on the government's Brexit strategy, marking a challenging week for Theresa May.
