Official results from the 7 May 2026 Hackney mayoral election, announced on 8 May, confirm Zoë Garbett of the Green Party as the winner with 35,720 votes, unseating Labour after 24 years of control and marking the party's first mayoral victory in London. This decisive outcome, tallied alongside the Hackney London Borough Council election, reflects voter shifts in the east London borough, propelling trader consensus to near-certainty on her victory. While residual probabilities linger on challengers like Vahid Almasi, Tareke Gregg, Eva Steinhardt, and Caroline Woodley, any realistic challenge would require a successful recount, legal dispute over ballot validity, or procedural irregularity—none of which have emerged in initial counts.
