Background
Lewisham is a south-east London borough bordered by Greenwich, Bromley, Catford, and Deptford. It has a population of approximately 310,000 and includes areas such as New Cross, Telegraph Hill, Forest Hill, and Brockley. Like Hackney, Lewisham has experienced rapid demographic change in recent years, with younger and more progressive households moving into areas historically characterised by working-class communities.
The Green Party selected Deptford, in the north of Lewisham, as the launch site for Zack Polanski's 2026 local election campaign in April, a deliberate signal that the Greens were targeting traditional Labour ground rather than comfortable strongholds. The Deptford launch was both a strategic statement and a geographic one: Deptford sits on the boundary of Lewisham and Greenwich, maximising media visibility across both boroughs.
On 7 May 2026, Liam Shrivastava won the Lewisham mayoralty for the Green Party, making Lewisham and Hackney the first two Green-controlled London boroughs in the party's history. The TWIN wins confirmed that the Green surge in London was not confined to a single demographic pocket and gave the party a platform for urban governance.
