As the Nationality and Borders Bill reaches committee stage in the House of Lords, this briefing by the Detention Taskforce sets out concerns about the impact of Part 5 of the Bill on victims of modern slavery. Measures dealing with identification and support for victims of crime do not belong in an immigration bill. Their inclusion risks muddling the two issues and undermining the Modern Slavery Act 2015. The briefing highlights particular clauses of concern and calls for the removal of Part 5 of the Bill and mitigating amendments.
