Question to the Home Office:

To ask the Secretary of State for the Home Department, how many and what proportion of people arrested for illegal working in January 2025 were (a) prosecuted and (b) convicted.

The priority with individuals found to be working illegally in the UK is to secure their removal from the country, in line with our normal procedures for returns and deportations.

The Home Office publishes data on returns in the ‘Immigration System Statistics Quarterly Release’, which can be found here: Immigration system statistics quarterly release - GOV.UK. This does not include a separate category for individuals arrested for illegal working, and that could only be collated and verified for the purposes of this question at disproportionate cost.
