However, relatively little of the net movement away from Leave was generated by direct switching from Leave to Remain. While 10% of those who voted Leave in 2016 said that they would now vote Remain, this movement was almost counterbalanced by the 7% of Remain voters who indicated that they would now vote Leave. The difference between these two figures generates an overall swing of 1% from Leave to Remain, too little on its own to overturn the result of the 2016 ballot.
By far the biggest single source of the swing – worth some 2% – came from the preferences expressed by those who did not vote in 2016 but who now state a voting intention. Roughly twice as many of this group (41%) say that they would vote Remain as state that they would back Leave (20%) –
a finding that echoes many another poll. Meanwhile, much of the rest of the movement arises because those who voted Leave in 2016 are much more likely than Remain voters to state that they definitely would not vote again and because Leave voters are also a little more likely to say that they are undecided how they would vote a second time around. In short, the central message of the poll is that, if there were to be another referendum, much would depend on who did and who did not make it to the polls. A second referendum is still far from guaranteed to produce the pro-Remain majority for which most of those campaigning for such a vote are apparently hoping.
