Undersea Internet Cables

Lord Rogan Excerpts

Thursday 16th January 2025 Lords Chamber

[Lord Mountevans (CB)]

My Lords—

[Lord Rogan (UUP)]

My Lords, how are we dealing with the threat to transatlantic undersea cables from hostile actors? Around 75% of the cables in the northern hemisphere pass through or near Irish sea waters. However, in a recent response to me on the Floor of this House, the noble Lord, Lord Vallance, seemed to suggest that the task of protecting these cables is carried out by a single ship which, with respect, does not sound remotely credible. As an esteemed Defence Minister, can the noble Lord advise me of what arrangements are actually in place to safeguard these cables serving the British Isles and how much of the bill is being paid by the Irish Government?

[Lord Coaker (Lab)]

I will leave what the Irish Government pay for to the Irish Government. Regarding the protection of critical underwater infrastructure, the UK has a large number of assets. The noble Lord of course points to the maritime assets that we make available, some of which we cannot discuss openly, but we also have surveillance aircraft and other means of protection. We will see in the defence review further suggestions as to what we might do in that respect. Let us make no mistake about it: one of the key functions of the Government is to protect the underwater infrastructure on which our livelihoods and prosperity depend. We will do that. It is not only about dealing with things when they happen but about deterring people from doing them in the first place. The Government will take the action necessary to achieve that.
