The results in the EU referendum on 23 June 2016 were reported by local authority, and, as the constituency consists of parts of two local authorities, the London Borough of Richmond upon Thames and the Royal Borough of Kingston upon Thames, the exact referendum vote in Richmond Park is not known. However, Chris Hanretty, a Reader in Politics at the University of East Anglia, estimated through a demographic model that Richmond Park had one of the dozen lowest 'Leave' votes in the entire country. His latest estimates suggest that 27.7% of Richmond Park voters voted 'Leave', and thus that 72.3% voted 'Remain'.
