Green Party Research Warns Labour Could Lose 50 Seats Over North Sea Drilling

Internal Green Party analysis shared with The Guardian on 19 August 2026 suggests Labour could lose up to 50 seats to the Greens if it approves new North Sea drilling. Over 50% of voters in every Labour-Green battleground constituency want faster climate action. Labour counters that projected Green gains have fallen from 20 seats to seven since Andy Burnham took office.
