What assessment he has made of the potential impact of his decision to retire HMS Bulwark and HMS Albion on the operational capability of the Royal Marines.

The retirement of HMS Albion and Bulwark will not impact the operational programme of the Royal Marines, who continue to deploy globally. Both are currently held at lower readiness having not been to sea since 2023 and 2017 respectively. On current planning, neither was due to go to sea again before their planned out of service dates of 2033 and 2034. The Royal Marines are supported by the three Bay Class Landing Ship Dock (Auxiliary)s and RFA ARGUS, which also provides aviation support and acts as a hospital ship. These ships will continue to support amphibious capability until they are succeeded by planned Multi Role Support Ships.

What estimate he has made of the cost of repairing the structural damage to HMS Devonshire.

There is no ship of the name HMS Devonshire currently in service with the Royal Navy.

What estimate he has made of the cost of the commercial service to bridge the availability gap for rotary capability in (a) Brunei and (b) Cyprus.

The Ministry of Defence signed a £122 million contract in 2024 to purchase six H-145 aircraft. These aircraft will replace the aging Puma aircraft to fulfil key capabilities in Cyprus and Brunei. A range of options are being explored to fill the capability gaps in the interim period before the arrival of H-145.

With reference to his Oral Statement of 20 November 2024 on Defence Programmes Developments, Official Report, columns 287-289, whether retention bonuses for Army personnel will be made available to the (a) Royal Navy and (b) RAF.

The Ministry of Defence pay retention payments in a variety of ways depending on the needs of the single-Services. Retention payments for the Royal Navy and Royal Air Force are targeted where they are most needed, and where they make the most efficient use of tax-payers money. From January 2025, a new £8,000 retention payment will be awarded to eligible regular Privates and Lance Corporals who have served four years. The payment targets Army Personnel as they enter a critical part of their career, with 12,000 personnel expected to benefit over the next three years.

With reference to his Oral Statement of 20 November 2024 on Defence Programmes Developments, Official Report, columns 287-289, whether he plans to extend the retention bonuses for aircraft engineers to non-aircraft engineers.

The single-Services each pay targeted retention payments where they are most needed, and where they provide the most efficient use of tax-payers money. As part of the Government’s commitment to renew the nation’s contract with those who serve, eligible Tri-service aircraft engineers will be given £30,000 when they sign up for additional three years’ of service. From April 2025, this will be applicable to around 5,000 personnel in total.

What proportion of the cost of running the UK-US military base in Diego Garcia was covered by the United States in financial year 2023-24.

It is not possible to determine relative proportions of the running cost of the base in Diego Garcia. The United States is responsible for any costs it incurs, while the UK remains responsible for the cost of the UK element of the base only.

What the cost to the public purse was of running the UK-US military base on Diego Garcia in financial year 2023-24.

The direct cost to the Ministry of Defence (MOD) for running the UK element of the UK-US military base in the British Indian Ocean Territory in financial year 2023-24 was £3.8 million. This excludes minor costs incurred directly by, for example, visiting units or HQ elements in the UK. Any costs incurred by other Government Departments cannot be provided by the MOD.

On what date he agreed his Department’s contribution to the Chagos Island settlement.

Negotiations between the UK and Mauritius on the exercise of sovereignty over the British Indian Ocean Territory/Chagos Archipelago were opened in 2022 under the previous Government. The lead Department for the negotiations was the Foreign Commonwealth and Development Office. My right hon.

The agreement secured with Mauritius protects the effective operation of the joint UK/US base on Diego Garcia for at least the next 99 years. Details of the Treaty agreed between the UK and Mauritius will come before Parliament for scrutiny in the usual manner following its signature. It would be inappropriate to release further details at this stage.

Pursuant to the Answer of 25 July 2024 to Question 121 on Armed Forces: Visas, when his Department first held discussions with the Home Office on ending visa fees for serving personnel.

Ministry of Defence officials began engagement with the Home Office in late July 2024 to discuss this manifesto commitment.

What assessment he has made of the potential impact of the agreement to cede sovereignty of the Chagos islands to Mauritius on the risk of espionage from hostile states.

The negotiations between the UK and Mauritius on the exercise of sovereignty over the Chagos Islands were announced in the House of Commons on 3 November 2022 by the then Foreign Secretary. Their aim was to ensure the continued effective operation of the joint UK/US military base on Diego Garcia. We now have this historic agreement, that ends the uncertainty over the future of the base on Diego Garcia, which plays such a crucial role in regional and international security. We have full Mauritian backing for robust security arrangements, including preventing foreign armed forces from establishing themselves on the outer islands, or otherwise undermining the effective operation of the Base, meaning the base is more protected than ever from foreign malign influence in a more insecure world.
