One in five (20%) British adults would consider voting for a new left-wing party founded by Jeremy Corbyn and Zarah Sultana. The party's appeal is strongest among young people, with one-third (33%) of 16-34s considering it, alongside a third of 2024 Labour voters (33%) and 43% of 2024 Green Party voters.

A new Ipsos in the UK poll reveals that the left-wing political party recently founded by former Labour leader Jeremy Corbyn and MP Zarah Sultana could capture a significant segment of the British electorate, particularly among younger voters and those who supported the Labour and Green parties in the 2024 General Election.

Overall, 20% of British adults say they would be ‘very’ or ‘fairly likely’ to consider voting for a new left-wing party. This figure, however, masks a sharp generational divide. A third (33%) of those aged 16-34 would consider voting for the new party, a figure that drops to 22% among 35-54s and just 9% among those aged 55 and over.

The potential for this new party to disrupt the existing political landscape is most evident in its appeal to voters of other left-leaning parties. One-third (33%) of those who voted Labour in 2024 and 43% of 2024 Green party voters would consider lending their vote to a Corbyn-Sultana-led party.
