My Lords, the Government keep the threat to undersea cables connected to the UK under close review, working to deter and mitigate identified risks. My noble friend will appreciate the limits to what can be said publicly, but the MoD constantly monitors activity within UK waters. This includes patrols conducted by Royal Navy assets, maritime patrol aircraft and the multi-role ocean surveillance programme. Following the strategic defence review, the Royal Navy will play a new leading and co-ordinating role, alongside the private sector, in securing undersea pipelines, cables and maritime traffic.
