The Illegal Migration Act 2023 is a law governing how the UK handles people who arrive irregularly, asylum claims, and removal decisions. It tightens government powers over detention, asylum procedures, and appeals, while introducing new requirements and reporting duties on safe and legal routes. During passage, the government won most changes, while opposition parties sought to curb detention of vulnerable people and to give more local authority input, with several Lords amendments rejected by the Commons and a number of government amendments agreed in the Commons and Lords before Royal Assent on 20 July 2023.
The bill completed its journey and received Royal Assent on 20 July 2023, after passing through both Houses. Lords amendments were debated and a number of government amendments were agreed in principle, culminating in a law that reflects a mix of tightened powers and several consequential or clarifying changes.
In the Commons, the Conservative government secured broad support and won the key votes, while Labour and most other opposition parties opposed many amendments and the main thrust of the bill. A string of Lords amendments were put forward and then disagreed by the Commons in multiple votes, reflecting a strong party alignment around the government’s approach, with a few provisions accepted as government amendments.
