- Defence Committee
Defence Committee scrutinises defence policy, military strategy, and the Ministry of Defence's spending and operations. The Commons Select Committee takes oral evidence from government ministers, military personnel, civil servants and external experts during regular public sessions. It examines major defence initiatives, spending decisions and operational matters affecting the armed forces. Recent inquiries have focused on UK defence capabilities in the High North, including testimony from academic experts and an expert panel on strategic positioning in that region. The Committee has also investigated the MOD's handling of a data breach involving Afghan Relocation Assistance Programme records, hearing from Williams and Lincoln, and pursued a follow-up inquiry into women in the Armed Forces. In parallel, it has assessed delays to the Defence Industrial Plan and its impact on defence industry capacity, whilst reviewing the MOD's Annual Report for 2024-25 with emphasis on reform priorities and undersea warfare capabilities including submarine and Bastion systems.

The Defence Committee session examined Ukraine’s conflict dynamics, emphasising the role of the defence-industrial base, rapid tech iteration, and private-sector collaboration in sustaining military aid. Witnesses argued Ukraine’s battlefield gains hinge on three pillars: innovation, unity of purpose, and European support, with the UK cast as a trusted ally and potential leader in defence collaboration. The discussion also explored defence procurement reform, the Defence Investment Plan (DIP), and the future of a ceasefire—contrasting good and bad outcomes amid shifting American support. Overall, the witnesses urged strengthened industrial and financial linkages with Europe and highlighted resilience as a critical social and economic dimension of modern warfare.

This Defence Committee session scrutinised the Afghan data breach, the ARAP/ARR/ACRS relocation schemes, and the cross-government response. Witnesses from the Ministry of Defence explained stabilising the schemes, risk assessments (notably the Rimmer review), and the decision to lift the super-injunction while planning to close the schemes by the end of this Parliament. They outlined data-protection improvements, a shift to self-moves, KPI governance, and cross-Government lessons to improve transparency and accountability.

The Defence Committee session scrutinised Russia’s Arctic strategy and the High North’s security dynamics, the UK’s role and leadership options (bilateral vs multilateral), and the capability gaps and strategic challenges faced by the UK and its allies. Witnesses emphasized the importance of NATO coherence while acknowledging valuable complementary roles for the Joint Expeditionary Force (JEF) and bilateral arrangements (notably with Norway and Canada). They highlighted significant UK naval capability shortfalls (submarine availability, frigate numbers, mine-countermeasures, airborne early warning, and weapons fit for platforms like F-35), the potential but limited and contingent value of autonomous/uncrewed systems, and the need for resilient defence-finance and stockpile approaches to sustain long-term campaigning. The discussion also underscored potential risks if US commitment wanes and the implications for extended deterrence in the High North. Overall, the witnesses argued for a pragmatic combination of leadership, allied collaboration, and ensured industrial capacity to deter and reassure in the Arctic region.

This session scrutinised the Afghan relocations and assistance policy (ARAP) data-handling risks, the scale of the ARAP and Triples schemes, the governance and accountability arrangements, and the steps taken to address a major data breach in August 2023. Witnesses David Williams (former Permanent Secretary, MOD) and Paul Lincoln (former Second Permanent Secretary, MOD) outline the origins of the risk, the shift from ad hoc spreadsheet use to dedicated casework systems (DACS) and Home Office platforms, and the challenges of cross-government coordination. They discuss the role of a cross-government SRO and a central co-ordination mechanism (the “gold group”), the impact of a super-injunction on parliamentary scrutiny, and the long shadow of accountability for decisions taken under crisis conditions. The discussion also covers cost implications (early MOD estimates of the breach around £850m), and the need for clearer outcomes and department-specific responsibilities to improve future crisis responses. The session signals a governance shift towards Cabinet Office-led cross-government coordination and an emphasis on clearly defined outcomes and accountability models in complex, multi-department schemes.

The Defence Committee’s 14 April 2026 session scrutinised progress on women in the Armed Forces five years on from the Atherton report, focusing on representation, culture, safeguarding, and accountability. Witnesses included the Minister for Veterans and People and the service chiefs. Key commitments and positions include: the government asserting substantial defence-spending commitments and progress on defence investments even before the Defence Investment Plan (DIP) is finalised; ongoing reforms to improve women’s representation, retention, and leadership opportunities across services; continued acceleration of capability improvements (e.g., ballistic-protection for women) and cultural-change mechanisms (leadership assessment, early-career education, ‘eight wells’ framework, and sense-and-warn data analytics); strengthened service- and civilian-complaints and victim-support systems (including the tri-service complaints unit, Victim Witness Care Unit, and the Armed Forces Commissioner); expansion of overseas victim-support, including deployments in Cyprus and Germany; and legislative planning via the Armed Forces Bill to enhance protections for victims. Despite improvements, the session highlighted ongoing concerns about persistent sexual harassment, safeguarding gaps at the Army Foundation College Harrogate, perceived gaps in confidence in the complaints system (86% of those harassed did not complain), and questions about leadership accountability for past failures in governance and data handling (Afghan data breach). The witnesses repeatedly emphasised data-driven, systemic, and cross-service approaches to cultural change and safeguarding, while Ministers signalled a continuing government-led, reform-driven agenda.
24 Mar 2026
The Defence Investment Plan delay was scrutinised for its tangible effects on industry, with witnesses from industry bodies and trade unions detailing a weakening demand signal, cash-flow stress for primes and SMEs, and risks to long-term capability. Defence sector witnesses described a “paralysis” in the ecosystem as large primes cannot flow contracts down the supply chain, and SMEs struggle with funding and planning. They warned of long-term consequences for skills, steel, submarines, and fast-jet production, and called for clearer, longer-term demand signals, “always-on” capability planning, and better alignment between the Defence Investment Plan and the Defence Finance and Investment Strategy. There was broad consensus on needing publication of the DIP (and the accompanying DFIS) and on keeping defence expenditure front-loaded with a sustainable, long-term pipeline, rather than arbitrary, short-term steps. Witnesses also pressed for better SME access to finance, a critical reassessment of fiscal tools (prefer DSRB to MDM), and stronger action on SME engagement, exports, and industrial capability. The session also highlighted industry concerns about decommissioning, energy costs, and skills pipelines (including neurodiversity and mid-career mobility). Quotes illustrate the immediacy of industry’s concerns and the urgency for delivery alongside policy design.
