A third of the UK electorate may consider tactical voting in the next general election, according to a survey by More in Common. This means that around 32% of voters might choose to support a candidate or party other than their preferred one in order to prevent another party from winning. The survey was conducted before news of two major donations to Reform UK, a right-wing political party, from crypto billionaires Ben Delo and Christopher Harborne, totaling £72 million. The findings come amid ongoing scrutiny of Reform UK, which has faced questions over its funding and an investigation into its leader, Nigel Farage, by the parliamentary standards commissioner. Luke Tryl, director of More in Common, said that many voters are "terrified" of a Reform UK government and are increasingly using tactical voting to block its rise. This trend is especially strong among voters on the political left. More than half of supporters of Labour, the Liberal Democrats, and the Greens are willing to vote tactically. In contrast, only 35% of Conservative voters and 30% of Reform voters are open to this approach. The survey also shows that a significant portion of left-wing voters are willing to support right-wing parties, mainly to stop Reform from gaining power. For example, 53% of Liberal Democrat supporters and 49% of Labour supporters would consider voting Conservative. Between 60% and 80% of Labour, Liberal Democrat, and Green voters are willing to vote tactically for at least one of the other progressive parties. Tryl noted that tactical voting is becoming more influential in shaping election outcomes, with recent by-elections in areas like Caerphilly and Gorton seeing voters prioritize stopping Reform over other considerations. Progressive voters, especially younger people and graduates, are more open to tactical voting than older or right-leaning voters. Majorities of Green, Labour, and Liberal Democrat supporters now see tactical voting as a viable strategy. Meanwhile, voters from the right, including those supporting the Reform and Restore parties, are less likely to engage in this practice. Tryl warned that a potential alliance or merger between the Conservatives and Reform could lead to a loss of votes, as their supporters may not align with each other. He also noted that while some Conservative voters are open to tactically voting for the Liberal Democrats, a majority of Reform voters might consider voting Conservative. Tryl added that tactical voting could be a major obstacle for Nigel Farage’s ambitions to become Prime Minister. Focus groups revealed that some progressive voters are deeply concerned about a Reform government and would support any candidate to prevent that outcome. With the left showing a willingness to vote strategically and the right struggling to unite behind Farage, Reform may face a significant challenge in the next general election.
