At GE2017 six times as many CON voters said Brexit was the deciding issue than LAB ones
Lord Ashcroft GE2017 on the day poll
Why LAB should worry less about supporters who backed leave
On general election day last year the Conservative peer, Lord Ashcroft, carried out a huge 14,000 sample poll to find out amongst other things why people had voted as they did and to tryto understand better what had happened. The survey was similar to US exit polls where much more than voting data is collected. The BBC/Sky/ITV UK exit poll is solely about predicting seats numbers and the election outcome.
One question to respondents was askingthem to state what was the main reason they had voted as they did. A summary of the key CON and LAB voter responses is in the graphic above.

As can be seen the most striking feature is the huge gap between Conservative voters’ views of the importance of Brexit and those of Labour voters
A total of 48% of those who had voted CON said Brexit compared with just 8% of LAB ones. We also cannot assume that the 8% were pro-Brexiteers. LAB picked up 30% of the GE2015 LD vote the vast majority of whom were opposed to Brexit

Perhaps it was the fact that Brexit was much less of a priority for LAB supporters that the majority of party’s gains from the Tories were in constituencies that had voted Leave a year beforehand at the referendum.
The poll asked people had voted and this was very close to the actual general election result which underlines the robustness of the findings.
