Russians cutting vital undersea cables, a rogue drone disrupting flights at airports and the assassination of a high-profile public figure are among the biggest threats facing Britain, a report warns today.
The National Risk Register outlined the “89 key threats to the UK's safety and security”, including the collapse of a social care provider, a cyber assault crippling the transport network and a military attack on a NATO ally which triggers the coalition’s self-defence clause.
The UK’s Deputy National Security Advisor Matt Collins said: “A comprehensive understanding of the risks we face is critical to keeping the UK safe. This edition of the NRR, based on the Government’s internal, classified risk assessment offers even more detail on the potential scenarios, response and recovery options relating to the risks facing the UK ranging from terrorism to conflicts and natural disasters."
Experts are increasingly worried about Kremlin submarines targeting underwater fibre optic connections linking Britain to the US.
“The reasonable worst-case scenario assumes that transatlantic subsea fibre optic cables connecting the UK would be damaged over a number of hours, rendering them inoperable. The primary sector impacted would be communications,” says the Register. “There would be considerable disruption to the internet, to essential services that rely upon offshore providers of data services (including financial services), and potentially to supply chain management and payment systems.”

Many cables connect the US and BritainWhile the internet would be back online within hours, full repairs would take months, planners warn. The Register also highlights the threat posed by a “malicious drone incident”. Hundreds of flights were grounded and tens of thousands of passengers’ journeys disrupted in 2018 when drone sightings were reported at Gatwick Airport.
The document also warns of the “severe disruption” that could be unleashed by a cyber hack of the transport system. “The attack could result in an immediate outage to services and systems, with potential for this outage lasting several hours and requiring multiple days for services to return to normal,” it says. “The disruption to critical services and systems could result in economic and reputational damage, as well as present an increased threat to passenger safety of the affected operators within or connected to the UK.”

It also raises fears about Vladimir Putin cutting off gas supplies to European countries - sparking a new price surge which could affect the UK, including electricity powering homes. Under the scenario, “all transit gas that flows from Russia to European states are cut off for several weeks during winter, potentially leading to demand curtailment across Europe; however, domestic heating will be maintained”. The Register says: “Increased gas prices may put certain energy-intensive industries at risk, but household bills are protected by the price cap. A severe gas shortage in mainland Europe for a significant period could also negatively impact continental European gas-fired electricity generation capacity, which could affect the UK’s security of energy supply in winter, impacting household electricity consumers.”
The potential impact of a nuclear attack on Britain is also war-gamed. “In the case of a nuclear event, the impacts would be catastrophic for the UK,” says the Register.
“There would be potentially widespread environmental damage and depending on the scale of the event, long-term exclusion of areas contaminated by radioactive material.” It adds: “The dissemination of radiological material has the potential for large numbers of casualties and fatalities in a relatively localised event.”
Deputy Prime Minister Oliver Dowden will launch the latest Register today during a visit to energy supplier SSE’s Able Seaton Port in Hartlepool. He said last night: “This is the most comprehensive risk assessment we've ever published, so that government and our partners can put robust plans in place and be ready for anything.”
