The What UK Thinks: EURef2 Poll of Polls is based on the average share of the vote for ‘Leave’ and ‘Remain’ in the six most recent polls of how people would vote if they were to be presented once again with the choice of either leaving the EU or remaining a member.
The bar chart to the right shows the average of the six most recent polls, the fieldwork for which was conducted between 30 April and 22 May 2019. It is based on two polls by Survation, and one each by BMG, Panelbase, YouGov and Kantar. The most recent addition is a poll conducted by BMG between 4 and 7 June 2019. The series had also been updated to include a poll by BMG that was conducted between 7 and 10 May 2019 but which was not published until 11 June 2019.
The line graph below shows how the Poll of Polls has changed since the beginning of 2018. The date at the bottom of the graph represents the date on which interviewing for the most recent poll in that set of six was concluded. Details of which companies’ polls are included in each estimate can be seen as you drag your cursor along the line graph.
Note the series includes both polls that were only conducted in Great Britain and those that were conducted across the United Kingdom as a whole. It also includes both those that asked people how they would vote in response to the question that appeared on the ballot paper in the June 2016 referendum and those that asked a slightly differently worded question.
