Liam Shrivastava

Liam Shrivastava won the Lewisham mayoralty on 7 May 2026, defeating incumbent Labour Co-op mayor Brenda Dacres in the same wave that saw Zoë Garbett take Hackney for the Greens. Together, Shrivastava and Garbett became the first two Green elected mayors of London boroughs in the party's history.

Lewisham has been a Labour stronghold for decades, with consecutive Labour mayors and a predominantly Labour council. Shrivastava's win reflects a Green surge across inner south and east London that YouGov's pre-election London MRP had projected, placing the Greens ahead in four London boroughs. Shrivastava, like Garbett in Hackney, built his profile through the local Green movement and community campaigning rather than through a prior national profile.

The Lewisham mayoralty carries substantial executive powers over planning, housing, and economic development. Shrivastava will govern a south-east London borough with acute housing affordability pressures, a significant young professional and student population, and a strong civil society network that supported the Green wave. How the new Green administrations in Hackney and Lewisham coordinate, and whether they can demonstrate a coherent alternative to Labour's inner-London model, will shape the Green Party's pitch at the next round of London local elections.
