UK’s Defence capabilities and aspirations inquiry launched

1 April 2022

The International Relations and Defence Committee is undertaking an inquiry into the Government’s ambitions for Defence, and their translation into reality.


The Committee’s inquiry will explore the Government’s ambitions for Defence set out in the March 2021 Defence Command Paper, and how these relate to the ambitions of the Integrated Review. It will assess how, one year on from publication, the Ministry of Defence is planning to translate the aspirations of the Defence Command Paper into reality, and will explore the extent to which the Russian invasion of Ukraine may have changed the UK’s assessment of the risk of conventional versus ‘sub-threshold’ warfare.

Focus of the inquiry

The Committee is seeking evidence on issues including:

  • The Defence Command Paper and its alignment with the Integrated Review
  • The types of warfare the UK Armed Forces are prepared to respond to, and comparisons with the capabilities of other NATO countries
  • The size of the Armed Forces
  • The UK’s assessment of and ability to respond to ‘sub-threshold’ threats
  • The extent to which Russia’s invasion of Ukraine has changed the assessment of risk
  • Technological innovation in Defence, including the potential role of ARIA
  • Whether cultural change is needed within Defence

For the full list of issues on which the Committee is seeking written evidence, please refer to the call for evidence.


The deadline for written evidence has been extended to  Friday 1 July 2022. The first oral evidence session will be held on Wednesday 6 April at 10.30am.
