Undersea cables

Inquiry

Undersea cables form the backbone of the world’s internet. The UK has around 60 cables which connect us to the outside world, carrying 99% of our data. Concern has been growing about the risk of these cables being sabotaged by foreign states. The consequences would be extensive. This inquiry will examine the UK’s ability to defend our undersea infrastructure, alongside the UK’s national resilience in the event of a major, protracted disruption to our internet connection.

This inquiry is no longer accepting evidence

The deadline for submissions was Thursday 13 March 2025.
