In a major U-turn, the UK government has ordered all Huawei technology to be stripped out of the UK's 5G network by 2027.
Prime minister Boris Johnson also banned the purchase of any new 5G equipment from the Chinese tech giant from the end of this year.
The government acknowledged the move would delay the roll-out of 5G in the UK by two to three years and increase costs by up to £2bn.
An existing ban on Huawei’s involvement in the most sensitive parts of the UK’s 5G networks – announced in January when the prime minister previously gave the go-ahead for the firm to build mobile infrastructure – remains in place.
Culture Secretary Oliver Dowden confirmed Tuesday’s further action on Huawei in a statement to the House of Commons, as he announced the measures would be put into law by a forthcoming Telecoms Security Bill.
He told MPs: “By the time of the next election we will have implemented in law an irreversible path for the complete removal of Huawei equipment from our 5G networks.
“We have not taken this decision lightly and I must be frank about the decision’s consequences for every constituency in this country; this will delay our roll-out of 5G.”
The measures introduced both in January and on Tuesday would cause a cumulative delay to the roll-out of 5G in the UK of two to three years and increase costs by up to £2bn.
Critics have long alleged Huawei has close links to the Chinese government and its equipment could be used for espionage purposes – something the company has always denied.
Huawei describes itself as a private company “fully owned by its employees”.
In January, Mr Johnson confirmed Huawei would be able to build “non-core” parts of the UK’s 5G network, but with a series of conditions attached to the company’s involvement.
This included capping Huawei’s market share at 35% and blocking it from involvement in the most sensitive areas of the network.
