National Security (State Threats) Bill Committee: Amendment 3

Parliament voted on Amendment 3 to the National Security (State Threats) Bill during its committee stage on 17 June 2026. The amendment was defeated by 317 votes to 85. The bill was being considered on the floor of the House, with the committee stage taken as a whole House rather than in a smaller committee room. The vote matters because it determines the shape of legislation aimed at countering state threats to the United Kingdom. The amendment's defeat means the relevant provisions will proceed without any changes it would have introduced. The bill amends the National Security Act 2023, and the specific clause at issue, clause 3, would add new sections to that Act, including proposed new section 33G, which has raised questions about its relationship to judicial oversight and access to the courts. The division was almost entirely along party lines. All 83 Conservative MPs who voted backed the amendment, joined by two Reform UK MPs, one Democratic Unionist Party MP, and one independent. Every Labour, Liberal Democrat, Labour and Co-operative, Green, and Plaid Cymru MP who voted opposed it, giving the government a comfortable majority of 232. There were no recorded rebels on the government benches.
