Nobody should live in fear of being snatched away from home
In the London borough of Lewisham, a Green Party-led council has uncovered evidence that national immigration enforcement sought to weaponize local public health data against restaurant workers — and has resolved to refuse. The discovery of a 2023 Home Office email requesting joint raids through environmental health channels has prompted a formal vote to sever all cooperation with immigration enforcement, the first step in an ambitious vision of a 'green crescent' of sanctuary boroughs across the capital. It is a moment that asks an old question anew: where does the duty of local government end and the conscience of a community begin?
- A quietly bureaucratic 2023 email — a Home Office officer asking Lewisham's food standards team to share inspection data for immigration raids — has exploded into a full political confrontation between local and national government.
- Labour's record of a 77% surge in workplace immigration raids since 2024 has galvanized Green-controlled councils, who swept five London boroughs in May and are now moving from protest to policy.
- Vulnerable workers in nail bars, takeaways, and restaurants face intensifying enforcement, while rough sleepers have previously been exposed through charity data-sharing — the human stakes behind the procedural language are acute.
- Lewisham's imminent vote, backed by a commanding 40 of 54 council seats, will mandate a sweeping review of all spending and data systems, potentially severing ties with organizations like St Mungo's over past migrant data disclosures.
- The Home Office is unapologetic, defending its information-sharing requests as legitimate intelligence-led operations — setting up a direct and unresolved collision between national enforcement authority and local sanctuary ambition.
When Lewisham's Green Party leadership uncovered a 2023 Home Office email asking the council's food standards team to share environmental health data for joint immigration raids on businesses, it transformed a symbolic commitment into a concrete confrontation. The email — direct and bureaucratic in tone — requested which council contacts could receive 'findings of interest' and whether raids could be conducted together. Next week, councillors will vote to review all council systems and contracts with the explicit aim of ending any cooperation with Home Office deportation efforts.
The vote is the opening move in what Green leaders are calling a 'green crescent' — a corridor of sanctuary boroughs across London. The Greens now control five London councils after May's local elections: Southwark, Haringey, Hackney, Lewisham, and Waltham Forest. They have capitalised on progressive anger at Labour's hardline immigration stance, which has produced a 77% increase in workplace raids since 2024 and an 83% rise in arrests — numbers ministers have publicly celebrated.
Researchers are more sceptical. The Migration Observatory's Peter Walsh has noted that while raids may deter some employers, the undocumented population likely numbers in the high hundreds of thousands — far beyond enforcement's reach. The operations are expensive, resource-intensive, and often reliant on tips of uncertain quality.
Lewisham had declared itself a sanctuary borough in 2021 under Labour. The Home Office email appears to have shattered any assumption that the declaration was more than symbolic. The forthcoming review will extend to external contracts, potentially affecting groups like St Mungo's, the homelessness charity that apologised in 2019 for sharing migrant rough sleeper data with immigration authorities.
Green leader Zack Polanski has framed the effort in terms of dignity — creating spaces where people need not live in fear of sudden removal. The Home Office, for its part, has defended its approach and made 'no apology' for seeking data-sharing partnerships with local councils. With the Greens holding 40 of Lewisham's 54 seats, the motion's passage is near certain. Whether it marks the beginning of meaningful local resistance to national enforcement — or remains largely aspirational — is the question Wednesday's vote will begin to answer.
Lewisham council's Green Party leadership discovered something that crystallized their opposition to government immigration enforcement: a 2023 email from Home Office officials asking the council's food standards team to help conduct joint raids on businesses, using environmental health inspection data as a targeting tool. The request was direct and bureaucratic—a Home Office immigration enforcement officer writing to ask which council contacts could receive "findings of interest" and whether raids could be conducted together. Next week, councillors will vote on a motion to review all council systems and contracts with the explicit goal of severing any cooperation with Home Office deportation efforts.
The vote represents the opening move in what Green Party leaders are calling a "green crescent"—a corridor of sanctuary boroughs across London where undocumented migrants would be shielded from enforcement action. The Greens now control five London councils after sweeping victories in May's local elections: Southwark, Haringey, Hackney, Lewisham, and Waltham Forest. The party capitalized on anger among progressive urban voters over Labour's hardline immigration stance, which has produced record numbers of workplace raids since the government took office two years ago.
The scale of that enforcement is striking. The Home Office reported a 77 percent increase in raids on businesses like nail bars, car washes, barbers, and takeaways since the 2024 election, accompanied by an 83 percent rise in arrests. Ministers have publicly celebrated these numbers as evidence of toughness on immigration crime. Yet researchers question whether the raids deliver meaningful results. Peter Walsh, a senior researcher at the Migration Observatory, noted that while workplace enforcement may deter some employers from hiring undocumented workers, the unauthorized population likely numbers in the high hundreds of thousands—far beyond what raids can reach. The operations remain expensive, resource-intensive, and often depend on tips of uncertain reliability.
Lewisham itself became a sanctuary borough in May 2021 under Labour leadership, formally announcing it welcomed migrants, asylum seekers, and refugees. The discovery of the Home Office email requesting cooperation appears to have shattered any remaining assumption that such declarations were more than symbolic. The motion coming to a vote will direct a comprehensive review of council spending and data systems. Party sources indicate the review will extend to contracts with external organizations, potentially affecting relationships with groups like St Mungo's, a homelessness charity that apologized in 2019 after admitting it had shared information about migrant rough sleepers with immigration enforcement.
Zack Polanski, the Green Party leader, framed the effort in terms of protection and dignity: councils working together to create spaces where people would not live in fear of sudden removal, regardless of their immigration status or documentation. The Home Office responded by emphasizing its "collaborative relationship" with Lewisham and defending raids as intelligence-led operations necessary to combat what officials call immigration crime. A spokesperson said the department made "no apology" for seeking information-sharing partnerships with local authorities.
The Greens hold 40 of Lewisham's 54 council seats, making passage of the motion virtually certain. What remains unclear is whether other councils will follow, and whether the Home Office will attempt to pressure councils into cooperation through other channels. The vote next Wednesday will test whether local government can meaningfully resist national immigration enforcement—or whether the sanctuary borough concept remains largely aspirational.

I'm proud of brave, compassionate Green councils in London working to create a corridor of sanctuary where nobody, no matter where they're from or what papers they have, has to live in fear of being snatched away from the place they call home.— Zack Polanski, Green Party leader
While all immigration enforcement visits are intelligence-led, we make no apology for joining forces with local authorities to enable information sharing and ultimately fighting criminals who fuel immigration crime.— Home Office spokesperson
A Conversa do Hearth Outra perspectiva sobre a história
Why did the Home Office think it could ask a council's food standards team for help with immigration raids?
Because environmental health inspections give you access to workplaces—restaurants, takeaways, nail bars. You're already inside. The Home Office saw that as a data source and a way to conduct raids without doing the legwork themselves.
And Lewisham only found out about this because someone uncovered an email?
Yes. The email was from 2023. It's not clear how long this had been happening or whether the council had actually cooperated before discovering the request. That's part of why they want to review all their systems now.
The Greens are calling this a "green crescent." Does that mean other councils will definitely follow?
It's an aspiration right now. The Greens control five councils, but that doesn't mean they all move in lockstep. Some may face different political pressures or legal constraints. It's a signal of intent, not a done deal.
What happens if a council refuses to cooperate but the Home Office finds another way to get the data?
That's the real question. A council can't control what the Home Office does independently. But they can control whether they're the ones handing over information, whether they're facilitating access, whether they're legitimizing it through partnership.
Is there any evidence these raids actually work?
Mixed at best. They may discourage some employers from hiring undocumented workers. But the unauthorized population is huge—hundreds of thousands. Raids touch a tiny fraction. They're expensive, they depend on tips, and researchers say the results don't justify the cost.
So why is Labour doing more of them?
Politics. Reform UK and other parties have pushed hard on immigration. Labour came to power promising to be tough on the issue. They're responding to electoral pressure, even if the evidence for effectiveness is weak.
