Question to the Home Office:

To ask the Secretary of State for the Home Department, what recent assessment she has made of the scale of illegal migration to the UK.

The Home Office publishes statistics on detected arrivals via illegal routes to the UK in the ‘Immigration System Statistics Quarterly Release’. Data on detected arrivals by illegal routes is published in table Irr_D01 of the ‘Irregular migration to the UK detailed datasets’, with the latest data up to the end of September 2025.

The Government has taken significant steps to address illegal migration and its Plan for Change sets out our ambition to secure borders and control immigration. We are committed to tackling illegal migration and the criminal networks which facilitate it. Since July 2024, nearly 50,000 individuals without lawful status have been returned from the UK. Our agreement with France means that those arriving by small boats can be detained and returned to France.
