What role the Office for Defence Exports played in the recent deal for Turkey to purchase 20 Eurofighter Typhoons.

What progress he has made on delivering the Shadow MK2 upgrade programme.

I can confirm that the Shadow Mk2 upgrade programme has been cancelled as it is late and has failed to deliver the capability that our Armed Forces need. It is also facing unacceptable cost escalation and delays.This decision will allow us to focus on investing in other defence priorities and the Shadow Mk1.We won't shy away from making difficult decisions that arise in the best interests of our Armed Forces and the taxpayer.

What discussions he has had with cabinet colleagues on the UK’s position in the event of military action by the United States against Venezuela.

I am withholding the specific criteria for achieving Full Operating Capability as it would harm the security and capability of the Armed Forces.

With reference to page 23 of the Defence Industrial Strategy: Making Defence an Engine for Growth, published on 8 September 2025, CP 1388, what progress he has made on determining which banks will form part of the defence industrial base.

Banks and other financial services companies, whose capital and expertise we need to invest and grow the defence sector, are being engaged in the development of the Defence Finance and Investment Strategy through the Defence Investors Advisory Group. This engagement informs both Government, industry and the investor community on what types of opportunity are appropriate, and how barriers to investment in defence can be removed while making the sector more attractive for private investment. This includes venture capital, private equity, banks and pension funds. This will deliver growth and strengthen the UK defence industrial base. The Defence Finance and Investment Strategy will set this out and is due to be published in early 2026.

What discussions has he held with the European Commissioner for Defence and Space on the potential merits of enhanced UK-EU cooperation under Security Action for Europe.

The UK is committed to a broad and constructive relationship with the EU. We are working to implement the package agreed at the UK-EU Summit and build on our landmark Security and Defence Partnership – which includes taking forward discussions on a bilateral participation agreement for enhanced cooperation under the EU’s Security Action For Europe (SAFE) instrument. As part of these efforts, the Defence Secretary continues to work constructively with all of our European allies, including with the European Commissioner for Defence and Space, to enhance Europe's defence industrial capacity and production and to deliver the critical capabilities to support Ukraine. We will not pre-empt the outcome of discussions with our European partners, this Government has been clear that we would only agree to a deal if we were satisfied it provided value to the UK and UK industry.

What assessment he has made of the potential impact of levels of (a) noise and (b) vibration on the (i) Ajax, (ii) Ares and (iii) Athena vehicles on the health of service personnel.

As safety of our personnel is the top priority for the Ministerial Team, prior to Ajax Initial Operating Capability being announced, I sought assurances in writing from the Chief of the Defence Staff and the National Armaments Director that the system was safe to operate, which I received.. As such, following the recent incident where noise and vibration symptoms were reported by some personnel operating Ajax, and out of an abundance of caution, I directed a pause on the use of Ajax for training and exercising, while a safety investigation is carried out. The Defence Accident Investigation Board are working with the Army Safety Investigation Team and General Dynamics at pace to conduct an investigation into the incident.

With reference to paragraph 11 of the Fifty-First Report of the Committee of Public Accounts, entitled The UK’s F-35 stealth fighter capability, HC 1232, for what reason the UK F-35 fleet achieved approximately one-third of the target for the time it was able to fly all its required missions in 2024.

The Ministry of Defence (MOD) does not release availability data for operational security reasons; the National Audit Office (NAO) reporting of this metric was also appropriately redacted for this reason. The standard availability metric used by the NAO assumes that the assets are available 24/7; which skews the metric when calculating MOD capability usage, particularly Combat Air, as we do not keep the assets airborne 24/7.There were a range of factors in the reported October 2024-January 2025 period including Force regeneration as part of standard Force Readiness cycles, and periods of planned personnel leave. This included a period when both Squadrons were deployed to a Carrier for an Exercise, routine post exercise regeneration with personnel leave and scheduled aircraft maintenance for many of the aircraft, and the Christmas and New Year leave period.
