Ministers have been warned that China could spy on millions of Brits by using microchips embedded in cars, domestic appliances such as fridges and even lightbulbs.
According to a report sent to the Government by a former diplomat who has advised Parliament on Beijing, the technology poses a "wide-ranging" threat to UK national security.
The report states that small modules gather data and transmit it via the 5G network, which gives the Chinese authorities intelligence and the ability to track people and businesses.
