The Liberal Democrats also oppose a third runway at Heathrow. They held the seat from 1997 until 2010, when Goldsmith won. They campaigned on an anti-Brexit position, noting Goldsmith's own support for Brexit whereas the area strongly voted for Remain in the 2016 EU membership referendum. The constituency is estimated to have had a 72% support for Remain. Goldsmith's is also expected to become a focal point of campaigning. The Liberal Democrat campaign started quickly, with leader Tim Farron first visiting the constituency on 26 October.
