Undocumented Workers
The question
To ask the Secretary of State for the Home Department, what estimate she has made of the number of individuals working without the legal right to do so in each of the last five years.
Answered by Alex Norris
The Home Office does not hold an estimate of the number of individuals working without the legal right to do so. Details of Immigration Enforcement activity to tackle illegal employment in the UK can be found in the Home Office’s published transparency data: Illegal working and enforcement activity to the end of September 2025 - GOV.UK
