Plans to introduce Britain’s Defence Readiness Bill, designed to prepare critical infrastructure and industries for potential conflict, have been postponed until at least mid-2027. The legislation, which ministers had initially promised for early 2026, will not be included in the government’s legislative agenda for the upcoming King’s Speech, scheduled after local elections next month.

The proposed bill aims to mandate key industries to prepare their workforces for potential wartime call-ups, empower ministers to enhance the reserve force, and designate essential infrastructure like energy networks and railways as military priorities. It is also intended to strengthen national resilience by ensuring civilian and commercial sectors can withstand attacks and support military operations, a core commitment under NATO’s Article 3.

The delay has been attributed by government departments to insufficient preparations for the legislation. However, the postponement has drawn sharp criticism from opposition parties and defence experts, who argue it risks "sending damaging signals to adversaries and allies" and leaves Britain out of step with several European nations that are moving faster on defence readiness.

Tan Dhesi, Labour chair of the defence select committee, which called for the bill's publication last November, emphasized its necessity for empowering the government to act during crises. He noted its absence in April and the lack of confirmation for its inclusion in the King’s Speech. Another Labour MP stated that the delay would further widen the gap in Britain's defences, citing recent global events as evidence the country is already behind.

James Cartlidge, the shadow defence secretary, described the situation as "dither and delay going from bad to worse" at a time when adversaries are rearming. James MacCleary, the Liberal Democrats’ defence spokesman, characterized the delay as a "dangerous signal of hesitation."

Despite the postponement, government sources maintain that progress can still be made without the immediate introduction of the bill. A government spokesman affirmed that national security remains a top priority, stating the UK possesses the necessary resources to ensure safety from attacks, domestically and abroad. The spokesman added that the approach to homeland security is continuously being hardened and sharpened, backed by the largest sustained increase in defence spending since the end of the Cold War.

Critics also point to the context of increasing geopolitical tensions, a "menacing global situation," and the likelihood of future conflict. They highlight that Britain’s armed forces are reportedly at a historic low in numbers and recruitment, with defence spending considered by some to be below required levels. A strategic defence review last year had underscored the urgency of preparing key industries and infrastructure for modern threats, including cyber warfare and asymmetric attacks, which have previously impacted critical sectors like airlines, hospitals, and power supplies. Other nations, particularly in the Nordic and Baltic regions, have accelerated efforts in defence spending and readiness.
