I in no way disagree with the noble Lord’s final conclusion. It is recognised across government, which is why a number of government departments have a role to play in protecting that critical national infrastructure. We certainly regard these installations as essential to our national infrastructure and monitor a variety of risks that they face. The noble Lord will understand that these subsea cables are predominantly owned and operated privately, but key departments work closely with their owners. Supporting that is the national risk register, the National Protective Security Authority and the National Cyber Security Centre. There is a comprehensive framework to support the private owners and operators of these cables, but the MoD has and discharges a critical role in monitoring threat.

My Lords, if, as is reported in the newspapers today, the plan is now to turn the whole north Atlantic into one gigantic system of wind farms on an international basis, the effect would be to turn the whole seabed of the north Atlantic into a cat’s cradle of vital undersea electric power lines. Are we prepared, in moving forward to this fossil-free electric world that we are heading for, to safeguard those lines, since they could, if interfered with, put at risk not merely 25% of our electricity supply but our entire electricity supply when the wind is blowing?

I think we all agree that the overall objective of increasing our usage of renewable energy is laudable and to be commended, but my noble friend is correct that the installation of infrastructure brings with it an obvious degree of risk. As I indicated to the noble Lord, Lord West, across government there are a range of departments with responsibilities in this field. As far as the MoD is concerned, we actively monitor threat. When it comes to looking at, for example, Russian activity in either the Baltic Sea or the North Sea, noble Lords will understand that we regularly assess by our maritime presence what is happening. The Russians know that we know they know what we are doing.
