Bishop of Leeds asks about response to Russian espionage

The Bishop of Leeds asked a question on UK response to potential acts of war by Russia, following a government statement on the Russian spy ship Yantar on 25th November 2025:

The Lord Bishop of Leeds: My Lords, it is clear that that message is conveyed, but it seems to do nothing to deter the Russians from continuing with their activity. Can the Minister say whether our military leaders have come to any conclusions about what an appropriate response will be to what, in the end, could be an act of war?

Lord Coaker (Lab, MoD): This is a really important question, but I say to everyone that we have to be really careful about the language that we use when we ask, “If this happened, what would we do? If that happened, what would we do? Would we see such and such as an act of war?” That is not to underplay the seriousness of what is happening, but it is about trying—as any Government would—to be reasonable and sensible in the language that is used.

Let nobody be in any doubt that the seriousness of this is significant. We know what the “Yantar” is doing as part of Operation GUGI, we know that it is surveying the underwater cables in a peacetime way for potential use in other scenarios in the future and we are making sure the Russians are aware of that.
