Labour MP Warns UK Exposed to Subsea Cable Threat

Labour MP Graeme Downie warned that the UK is dangerously exposed to disruption of its undersea cable network. He cited the Joint Committee on the National Security Strategy, noting that about 98% of internet traffic travels through these cables, making them critical for hospitals, finance and air traffic. While a coordinated catastrophic attack is unlikely, even limited interference could cripple mobile networks, digital payments and supply chains. Downie urged adoption of seabed sensors, AI monitoring and naval assets such as Type‑26 frigates and P‑8 aircraft, and called for allied cooperation to protect the global cable system.
