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 5 December 2019 and 31 January 2020. It is based on two polls by BMG, and one each by Survation, YouGov, Panelbase, and Deltapoll. The most recent additions are a poll conducted by YouGov between 14 and 20 January 2020 and a poll conducted by Survation between 30 and 31 January 2020.

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.
