On May 29, 2026, the UK government announced plans to impose stricter penalties for damaging subsea internet cables, which are crucial for national infrastructure. Telecoms minister Liz Lloyd highlighted that subsea cables handle over 99% of international data traffic and support £1.4 trillion in daily financial transactions. Recent intelligence revealed covert Russian submarine operations near these cables, prompting the need for legislative updates to deter sabotage. Proposed changes include tougher fines and prison sentences for reckless damage, as well as new security obligations for cable operators. The government aims to eliminate legal ambiguities surrounding malicious activities and enhance rapid response capabilities to incidents. Additionally, a consultation will explore the establishment of a British-flagged repair ship and the review of environmental regulations to expedite new cable installations. These measures are part of a broader strategy to safeguard the UK's digital economy from hostile actions.
