A Home Office request to Lewisham’s food standards team has turned a local council procedure into a wider fight over data, deportation raids and Green-led sanctuary politics.
The dispute in Lewisham is not only about immigration rhetoric. It is about whether information gathered by local council services should help Home Office enforcement teams carry out raids and removals.
According to Guardian reporting, councillors in the Green-led London borough were due to vote on a motion to review council systems with a view to ending cooperation with government efforts to deport people without the right to remain in the UK. Critics of Green sanctuary policies argue that such non-cooperation can weaken enforcement against illegal working and immigration crime. Supporters argue it protects trust in local services.
Why one Home Office email matters
The immediate flashpoint was an email from the Home Office’s immigration enforcement team to Lewisham’s food standards team.
The email asked for contacts and raised the possibility of “joint operational visits.” Green councillors and migration advocates treated that as evidence that routine council work, including environmental health activity involving restaurants, could become linked to immigration enforcement.
That connection is the core of the argument. Local authorities collect information through services such as housing, safeguarding, licensing, public health and environmental health. Sanctuary campaigners say people with insecure immigration status may avoid reporting unsafe conditions if they believe contact with the council could lead to enforcement action.
Opponents see a different risk. They argue that withholding cooperation from immigration authorities can make it harder to identify illegal working, exploitative employers and criminal activity connected to immigration offences.
What Lewisham’s motion would do
The Lewisham proposal would review spending, data collection and operational systems with the aim of stopping council resources from assisting Home Office immigration raids.
If approved, it would not change national immigration law. Ministers would still be able to enforce removals. The practical change would be in how one London borough shares information and works with Home Office teams.
The motion was expected to pass, according to the Guardian, because the Greens hold 40 of Lewisham council’s 54 seats.
That local arithmetic is why the vote has wider significance. A council motion about data-sharing could become a model for other Green-led or Green-influenced boroughs that want to separate public services from immigration enforcement.
Both sides claim the public-safety ground
The Home Office has defended cooperation with councils as a tool for enforcement. According to a spokesperson quoted by the Guardian, the department said it had a “collaborative relationship” with Lewisham council, that immigration enforcement visits are intelligence-led and that it makes no apology for information sharing that helps fight “criminals who fuel immigration crime.”
That argument presents workplace and premises visits as part of a wider effort to disrupt unlawful hiring and exploitation.
Sanctuary advocates counter that enforcement links can make vulnerable people less visible to the very local services meant to protect them. In their view, a worker who fears deportation may be less likely to speak to inspectors about unsafe conditions, overcrowding, abusive employers or rogue landlords.
The factual dispute is therefore not simply enforcement versus no enforcement. It is whether council cooperation improves detection of harm or pushes people away from help.
Green leaders frame the policy as sanctuary
Green politicians have presented the London push as a sanctuary approach rather than as a formal abolition of borders. The hostile label “open borders” is used by critics; the Lewisham question is more specific: should council staff, systems and data assist Home Office removals?
Zack Polanski, the Green Party leader, praised Green-led London councils in the Guardian’s report for trying to create what he called a corridor of sanctuary. He said he was proud of councils working so that nobody, regardless of where they are from or what papers they have, has to fear being removed from the place they call home.
That message resonates with supporters who believe immigration enforcement has become too punitive. It alarms opponents who believe councils should not obstruct national enforcement, particularly where the Home Office says raids target illegal working and immigration crime.
The argument is now being tested in practical council administration. Green-led local government is moving from campaign language into decisions about contracts, staff instructions and data flows.
The national backdrop is tougher enforcement
Lewisham’s vote sits against a national rise in immigration enforcement activity. The Home Office said in January that raids on businesses such as nail bars, car washes, barbers and takeaways had risen by 77% since the 2024 election, while arrests had risen by 83%.
Labour is under pressure from voters and Reform UK to show a tougher approach on immigration. Green-led councils are moving in the opposite direction by seeking to limit the role of local services in national enforcement.
Peter Walsh, a senior researcher at the Migration Observatory, told the Guardian that workplace enforcement can make employers think twice about hiring people without the right to work.
He also noted that, with the unauthorised population likely in the high hundreds of thousands, raids can reach only a small share of the businesses involved. Reporting has suggested such raids are expensive, resource-intensive and dependent on tipoffs of varying quality.
What remains unresolved
The hardest questions are operational. Would Lewisham share information where trafficking, violence or serious exploitation is suspected? How would staff distinguish immigration enforcement from safeguarding? Would the Home Office seek the same information through other channels?
Past cases explain why campaigners focus on data. The Guardian report cited evidence that child protection services in Sussex had worked with immigration enforcement to gather data on unaccompanied child asylum seekers. It also noted that the homelessness charity St Mungo’s apologised in 2019 for sharing information about migrant rough sleepers with the Home Office.
Those examples are why sanctuary advocates want a broad review of council systems. Critics will ask whether broad non-cooperation could block legitimate work against exploitation and unlawful employment.
The outcome in Lewisham will show how far a Green-led council is prepared to go in separating local services from immigration enforcement. It will also test whether sanctuary politics can be turned into workable rules without undermining efforts to police abuse and illegal working.
