The exclusive poll, reported by The Guardian, represents a significant boost for those within Number 10 who favour negotiating a path back into the bloc. The data provides clear evidence that a pro-European stance could be a major electoral asset.
However, the findings also highlight a deep strategic rift within the government. Cabinet ministers, acutely aware of the political and social upheaval caused by the 2016 referendum and the subsequent years of negotiations, are privately urging the prime minister to proceed with extreme caution.
The poll tested the scenario of a fresh referendum, a move that the data suggests could dramatically shift the electoral landscape. The central challenge for the government is now balancing the evident public appetite for closer EU ties against the risk of reopening a national debate that previously left deep scars on the body politic.
