Lewisham Council has become the first local authority in the United Kingdom to refuse to help the Home Office carry out immigration enforcement raids. The decision was approved at a full council meeting on 28 January 2026. The council is run by the Green Party, and its promise applies "wherever legally possible" — meaning the council will refuse to help only in situations where the law allows it to do so. The commitment covers help the council gives through licensing (checking businesses are properly registered) and environmental health inspections (BBC News; Lewisham Council).

The idea was put forward by Green councillor Hau-Yu Tam, whose council role covers communities, sanctuary and healing. The council published an official announcement on 23 July 2026 confirming the motion had been approved, saying it would strengthen support for migrant communities and review cooperation with immigration enforcement (Lewisham Council). The council meeting agenda on 28 January 2026 included a commitment to refuse to provide assistance to the Home Office or Immigration Enforcement teams, including through council licensing and environmental health duties (Lewisham Council meeting documents).

The decision comes after a sharp rise in enforcement activity across London. Home Office immigration enforcement teams carried out 2,715 raids and illegal working visits in London during 2025, resulting in 2,172 arrests. By comparison, there were 2,008 enforcement raids in London in 2024 (BBC News).

Cllr Tam's opposition is based on specific incidents in the area. In January 2026, immigration raids took place at a nail bar in Catford and a car wash in Brockley. The Brockley car wash raid was attended by the then immigration minister Mike Tapp and a Sky News film crew. Cllr Tam said only two people were arrested across the two raids, and both were later released on bail (BBC News).

A nail bar in the Lewisham area was raided again a few months after the January 2026 operation, and then again a few days later. Cllr Tam said that according to local accounts, Chinese women workers were filmed, handcuffed, and intimidated by a large team of officers during a raid but were not arrested (BBC News).

Cllr Tam called the immigration enforcement operations "political theatre" and "a theatre of cruelty". She said there is no evidence the operations are making the community safer. "Our immigration system is broken," she said (BBC News).

The broader context here is about who controls immigration and who actually carries it out. Immigration policy is decided by the UK government in Westminster — local councils do not set the rules. But when the Home Office carries out raids, it often needs help from local councils, such as checking whether a business is properly licensed. Lewisham's motion tests how far a council can go in refusing to help. The phrase "wherever legally possible" matters because councils cannot ignore legal duties placed on them by central government.

The precedent is narrow but important. One Green-led council refusing to cooperate is not a national policy change. But it creates a template that other councils with similar politics may look at. The fact that a serving immigration minister attended a televised raid in Brockley adds a political dimension that Cllr Tam's "political theatre" description speaks to, whether or not one agrees with it.

The enforcement figures provide the backdrop against which Lewisham's stance will be judged. A 35 per cent increase in London raids from 2024 to 2025, along with an arrest rate of roughly 80 per cent, suggests an enforcement system working at a large scale. Whether that scale actually makes communities safer, as Cllr Tam says it does not, is a question the available data does not answer.

What remains is a council drawing a line on practical cooperation while acknowledging it cannot legally block enforcement. The Home Office keeps its powers. Lewisham keeps its political stance. The tension between the two is unresolved, and the legal limits of "wherever legally possible" have yet to be tested in practice.
