A quarter (25 percent) of those surveyed who backed the Labour Party in the 2024 general election said they will now back the Greens. A third (37 percent) said they would continue to support the governing party.

The study found that the Greens, whose membership numbers have surged since Zack Polanski became leader last September, are the most popular political party in all age categories under 50. Nearly half (49 percent) of 18 to 24-year-olds and just over a quarter (27 percent) of 25 to 29-year-olds said they would back the party.
