Opinion polls play a central role in modern British elections, being prominent in the media reporting of the campaign, increasingly so in recent years. Many of the voters seem to be interested in the polls, but whether they have a significant impact on voting behavior remains unresolved. Despite past suggestions that polls are inherently populist, they seem to have played only a limited role in the U.K.'s vote to leave the European Union ("Brexit"). Support for Brexit was rooted in existing political attitudes and brought to a peak by populistic exploitation of discontent with the establishment.
