Crime and Policing Bill: motion to disagree with Lords Amendment 359

MPs voted 277 to 158 on 14 April 2026 to reject a Lords amendment that would have required the government to conduct a formal review of whether to proscribe Iranian government-related organisations, including the Islamic Revolutionary Guard Corps (IRGC). The government's motion to disagree with Lords amendment 359 passed, meaning the requirement for such a review will not form part of the Crime and Policing Act 2026. The vote blocks a statutory obligation on ministers to assess whether the IRGC and related organisations should be added to the list of proscribed terrorist groups. Proscription under UK terrorism law makes membership and support for a designated organisation criminal offences. Rejecting the amendment preserves ministerial discretion over which groups are considered for proscription, keeping that process outside of any compulsion set by Parliament. Labour and Labour Co-operative MPs voted solidly for the government's position, providing all 273 of the aye votes from those two groups combined. Conservative MPs voted 84 to zero against, joined by the Liberal Democrats (58 against), the DUP (5 against), the Greens (4 against), and Plaid Cymru (3 against), forming an unusual cross-party bloc in favour of the Lords amendment. One Liberal Democrat MP voted with the government, and four Independents also voted aye. The division sits within a wider set of contested exchanges between the Commons and Lords over the Crime and Policing Bill, with related votes continuing into late April 2026.
