Cyber Security and Resilience (Network and Information Systems) Bill Remaining Stages: Amendment 3

Parliament voted on 16 June 2026 on Amendment 3 to the Cyber Security and Resilience (Network and Information Systems) Bill at its remaining stages. The amendment was defeated by 246 votes to 162. Every Labour and Labour and Co-operative MP who voted opposed it, while Conservatives, Liberal Democrats, Greens, Plaid Cymru, the Democratic Unionist Party and most other opposition parties voted in favour. The bill updates the United Kingdom's rules on network and information systems security, extending obligations to more organisations and sectors classed as critical infrastructure. Amendment 3 sought to alter the bill's provisions in this area, and its defeat means the government's original text on that point will stand. The outcome affects businesses, public bodies and infrastructure operators who fall within the bill's scope, determining what security duties they must meet and how those duties are enforced. The vote followed clear party lines. All Labour MPs voted against, providing the government with a comfortable majority. The opposition was unusually united, with Conservatives and Liberal Democrats both voting in favour of the amendment alongside the Greens, Plaid Cymru and the DUP, forming a broad cross-party bloc that nonetheless fell well short of a majority. This division was one of several on the same day; earlier votes on New Clause 13 and New Clause 14 were also defeated, with the government winning by larger margins on those occasions, suggesting Amendment 3 attracted slightly more opposition support but still could not overcome Labour's numerical advantage in the Commons.
