Undersea Cables

Lord Berkeley Excerpts

Thursday 8th March 2018 Lords Chamber

Asked by

[Lord Berkeley]

To ask Her Majesty's Government what steps they are taking to improve the security of undersea cables linking the United Kingdom with the United States and other countries.

[The Parliamentary Under-Secretary of State, Department for Digital, Culture, Media and Sport (Lord Ashton of Hyde) (Con)]

My Lords, submarine fibre optic cables play an essential role in the ecosystem of a successful internet-based economy. That is why, as part of our programme to protect the UK’s communication infrastructure, the DCMS is working closely with industry to improve the security and resilience of the UK’s submarine cable network. This includes assessing the physical, personnel, and cyber risk to subsea cables, and offering recommendations to cable operators to mitigate them.

[Lord Berkeley (Lab)]

My Lords, I am very grateful to the Minister for that Answer. I think his department has got some way to go, though. He may recall that, about a month ago, a journalist from the Sunday Times walked into a farmhouse in Cornwall through an open door and photographed all the connections to one of the main submarine cables. Last summer, a ship dropped its anchor on a cable between the Isles of Scilly and the mainland and cut the cable, and nobody has bothered to prosecute it. Will he explain whether the Government really are taking seriously the issue of security on these cables, and what will they do ensure that the two instances I have just exemplified will not happen again?

[Lord Ashton of Hyde]

The noble Lord raises an important point. As far at the Sunday Times report is concerned, I can say that the reporter was unable to access any secure section of the facility. The essential point about this is that there is resilience in the system. There are 11 landing sites, for example, for transatlantic cables, in different places. Because of the resilience of the system, when one particular cable is broken the system continues. As far as prosecution is concerned, most of the breaks in the cables—and there are a considerable number each year; about 30 to 40 each year—are as the result of accidents. That is why it is not normally necessary to prosecute. However, these are civil actions because the cables belong to individual companies. It is up to them to seek damages.
