Megapoll finds nearly half of voters support UK rejoining EU
A Messina Group poll found that almost half of voters support Andy Burnham’s reported preference for the United Kingdom to rejoin the European Union after the next election. The findings also indicated that reopening the relationship could increase Labour’s vote share by as much as seven points if a fresh referendum were offered and the prime minister campaigned to re-enter the bloc.
Almost half of all voters support Andy Burnham’s personal preference for the United Kingdom to rejoin the European Union after the next election, according to a new megapoll by the Messina Group.
The poll examined the potential electoral effect of renegotiating the UK’s relationship with the EU. It found that Labour’s vote share could rise by as much as seven points if the prime minister offered a fresh referendum and campaigned for the country to re-enter the bloc.
The findings are expected to strengthen the position of people in No 10 who want negotiations on re-entry. However, some senior figures remain cautious about reopening divisions created by Brexit.
Cabinet ministers concerned about those divisions are privately urging Burnham to proceed with caution, according to the source report. The supplied findings do not provide further details about the poll’s methodology, the number of respondents, or the precise level of support for rejoining the EU.
