The Wavering Wall: The impact of undecided voters on Britain's next general election

New analysis by Best for Britain suggests that despite a consistent 20pt poll lead, Labour is on course secure a majority of 56-58 seats. This landmark report on the ‘Wavering Wall’ shows undecided voters lean heavily Tory and are projected to swing more than 160 seats in a General Election. The report has raised concerns that any narrowing of the polls over the next two years could cost Labour the next election. This landmark report into undecided voters found that despite the Labour Party’s consistent 20 point lead in the polls in the latter half of 2022, it would deliver them a UK parliamentary majority of fewer than 60 seats. A 10,010 person MRP poll by Focaldata taken around the resignation of Liz Truss and updated with a 2,000 person MRP poll after Rishi Sunak became Prime Minister, showed that the Labour Party’s current lead among voters would secure them more than 500 seats in a General Election, echoing the forecasts of many other recent polls. However, many seat projections do not factor in people who respond ‘Don’t Know’ when asked how they intend to vote at the next election, despite relatively high numbers choosing this option over the past few months. In the top up poll by Focaldata, 10% of respondents said they were unsure who to vote for.
