North Atlantic Submarine Activity

Tanmanjeet Singh Dhesi Excerpts

Monday 13th April 2026 Commons Chamber

[Madam Deputy Speaker]

I call the Chair of the Defence Committee.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

I thank the Minister for his statement and the Defence Secretary for his public statement, which have increased public awareness about the growing threats that our nation faces. On behalf of the Defence Committee, I pay tribute to all our armed forces personnel involved in disrupting the Russian activity around our critical undersea infrastructure. This incident underscores the growing threat that Russia poses, and the need to increase defence investment now and finally to publish the defence investment plan.

Turning to the incident itself, I take on board the Minister’s words, but it has been widely reported, including publicly at the London defence conference, that Putin had explosives planted on our undersea cables. For the record, can he confirm whether Russians were involved in either sabotage or precursors to sabotage on or around our undersea cables?

[Al Carns]

The reality is that Russia failed on this occasion, and it failed because we exposed its activity, which meant that there was no way, shape or form that it could deny its activity in the first place. I was at the London defence conference and I heard certain discussions about undersea cables. I can confirm that no sabotage took place this time, but the Russians put a lot of effort into mapping and understanding our undersea critical national infrastructure, and we will do everything to map, track and expose it, should it take place.
