London, UK – Britain’s critical infrastructure may be more vulnerable than ever to Chinese interference, according to Sir Richard Dearlove, the former head of MI6. In an exclusive interview with The i Paper, Dearlove warned that China could bring the UK to a standstill by exploiting the very technology embedded in devices that Britons rely on every day. From electric cars to traffic lights and even hospital equipment, the former intelligence chief outlined the risks that could arise from Britain’s growing dependence on Chinese-made technology.
A National Security Crisis Waiting to Happen
Sir Richard, who served as the head of MI6 from 1999 to 2004, expressed his concern that China’s presence in critical UK technologies could allow Beijing to control essential infrastructure at will. Describing the situation as “sleepwalking into disaster,” he highlighted that Chinese companies are increasingly manufacturing microchips embedded in everything from electric cars and solar panels to industrial fridges and traffic lights.
“Imagine immobilised cars, zombie traffic lights, or solar panels that suddenly stop working. That’s the potential threat,” Dearlove said. “This isn’t a conspiracy theory; it’s a very real risk that the UK is running.”
These microchips, known as Cellular Integrated Modules (CIMs), are part of the broader Internet of Things (IoT) ecosystem, which connects devices to the internet and allows them to transmit and receive data remotely. According to Dearlove, the Chinese government could exploit this technology to disrupt UK cities by remotely disabling devices critical to daily life.
A Vulnerable Nation
“If China wanted to bring London to a halt, it could,” said Dearlove. “You could switch off the entire traffic light system in the city or immobilise electric cars parked on the main streets. It would be chaos.”
But the threat doesn’t stop at traffic or transportation. The UK’s energy grid, especially in its reliance on renewable technologies like solar panels, could also be disrupted. “A black-out could be triggered if key Chinese-manufactured components in the power grid are turned off or malfunction,” warned Dearlove.
The former intelligence chief’s fears are not unfounded. Last week, Reuters reported that hidden communication equipment had been found in Chinese-made batteries used to connect solar panels to US power grids. These unauthorized components, which could bypass security measures, had the potential to trigger widespread power outages.
Technology vs. National Security
In an impassioned critique, Dearlove also targeted former Energy Secretary Ed Miliband’s “ideological” net-zero policies, which, according to him, have worsened the nation’s vulnerability by making the UK increasingly reliant on Chinese technology.
“The problem is that Miliband and others are pursuing net-zero policies without considering the national security implications,” he said. “The reliance on Chinese-made technology in energy systems is an open invitation for sabotage.”
The UK government has been aware of these threats, but its response has been slow. Earlier this year, the Ministry of Defence banned electric vehicles containing Chinese-made components from being used at sensitive military sites, citing national security concerns. In 2020, the UK government also banned Huawei from working on the country’s 5G network after it became clear that the Chinese tech giant could potentially be used as a channel for espionage.
However, Sir Richard believes that the government’s response has not been sufficient. “We should have acted much earlier, as Australia and the United States did, to protect our critical infrastructure,” he said.
China’s Global Strategy
Sir Richard’s concerns also point to a broader geopolitical struggle. The former MI6 chief suggested that the UK is a target of China’s strategic ambitions, part of Beijing’s long-term goal to “dominate global science and technology” by 2049.
“The Chinese government has a clear, strategic ambition to displace the West, particularly the United States,” Dearlove said. “They’re using technology as the primary forum to gain power and influence.”
In the face of these mounting concerns, the UK is trying to balance national security with the economic benefits of investment from China. The UK government has recently acknowledged the need for a comprehensive strategy to protect national interests while engaging with China. Reports indicate that the government is conducting an audit to better understand the scope of the UK-China relationship, with an eye on strengthening cybersecurity and resilience.
A government spokesperson told The i Paper, “Protecting national security is our top priority. We already have one of the most robust product security regimes in the world, and we will not hesitate to act where necessary.”
A Call to Action
In response to these risks, Dearlove and other experts, including Charles Parton from the Coalition on Secure Technology (CST), have been pushing for greater awareness of the potential threats posed by Chinese technology. Graeme Downie, a Labour MP and chair of CST, warned that devices could be remotely controlled and reprogrammed to cause disruption, as simple software updates could render refrigerators, air-conditioning units, or even entire power grids useless.
“China has access to over 5 billion integrated modules in devices across the world. If they wanted to, they could remotely switch off cooling in hospital fridges, potentially destroying vital medicines and vaccines,” said Downie.
With over 65% of these modules manufactured in China, the risks are mounting, and experts are calling for stronger measures to mitigate these vulnerabilities.
The Road Ahead
As tensions between the UK and China escalate, the government has vowed to introduce a Cyber Security and Resilience Bill to better protect the British public. However, the question remains whether these measures will be enough to protect the UK from the growing influence of Chinese technology.
In the meantime, Sir Richard Dearlove’s warning remains stark: “The UK must act now to reduce its dependence on Chinese technology. We need to think about the future and how we can protect ourselves from a growing global threat.”
The UK government is facing an uncomfortable choice, can it safeguard its national security while still engaging with China, or will the risks of Chinese technological domination prove too great to ignore?
