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

**What happened:** The House of Commons voted on 14 April 2026 to reject a Lords amendment to the Crime and Policing Bill that would have formally proscribed Iran's Islamic Revolutionary Guard Corps (IRGC) as a terrorist organisation. The motion to disagree with Lords Amendment 359 passed by 277 votes to 158, with the government's position prevailing. **Why it matters:** Proscription of a group as a terrorist organisation under UK law carries significant legal consequences, including making membership, support, and fundraising for the group criminal offences. The Lords amendment would have placed the IRGC in the same legal category as groups such as al-Qaeda or Hizballah. By rejecting the amendment, the government preserved the status quo in which the IRGC is not formally proscribed, and instead pointed to existing measures, particularly the foreign influence registration scheme, as the appropriate tools for addressing threats posed by the organisation. Critics argued those tools are insufficient given the IRGC's alleged activities on British soil. **The politics:** The vote divided largely along government-versus-opposition lines. All 248 Labour MPs and all 26 Labour and Co-operative MPs who voted backed the government's rejection of the amendment. The Conservative Party, all 84 of its voting members, backed the Lords amendment, as did 58 of 72 voting Liberal Democrats. Notably, one Liberal Democrat voted with the government. The Democratic Unionist Party, Plaid Cymru, the Green Party, Ulster Unionist Party, and Traditional Unionist Voice all voted against the government. The division reflects a recurring tension in the bill's passage, with related votes on 20 April 2026 showing a similar pattern of around 290 ayes to 158 noes as the bill continued its parliamentary journey between the two chambers.
