Question to the Home Office:

To ask the Secretary of State for the Home Department, what estimate his Department has made of the number of irregular migrants that will enter the UK via the English Channel in each of the next five years following the passing of the Border Security, Asylum and Immigration Bill.

An impact assessment of the Bill is published at https://www.gov.uk/government/publications/border-security-asylum-and-immigration-bill-2025-impact-assessment.

This includes analysis of how the new powers in the Bill could achieve the intended impacts, including by leading to more effective interventions in disrupting and prosecuting those who seek to facilitate irregular migration to the UK. The Home Office will continue to monitor and evaluate measures within the Bill once they have been implemented, subject to Parliament’s approval.
