Opinion polling on the United Kingdom's membership of the European Union (2016–2020)
Following the referendum in the United Kingdom on its membership of the European Union on 23 June 2016, polling companies continued to use standard questions in order to gauge public opinion on the country's relationship with the EU. Opinion polling overall showed an initial fall in support for Brexit from the referendum to late 2016, when responses were split evenly between support and opposition. Support rose again to a plurality, which held until the 2017 general election.
