Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what steps he is taking to protect (a) undersea cables and (b) critical maritime infrastructure.

We are committed to maintaining and enhancing the security and resilience of critical undersea infrastructure including subsea cables. We continue to co-ordinate with HMG partners, particularly DSIT and DESNZ who own critical undersea infrastructure policy, as well as security partners, industry, and international bodies to assess and understand risks to this infrastructure.

On 22 January 2025, the Secretary of State made a statement in the House about the malign activities of the Russian Spy Ship Yantar and efforts by the RAF, Royal Navy and the RFA to deter Russians loitering over UK critical underwater infrastructure.
