Prime Minister Boris Johnson is set to strike a major policy change after GCHQ is believed to have reassessed the risks posed by the Chinese tech company, acording to reports.
A study set to be presented to Mr Johnson this week will declare that US sanctions on Huawei will force the company to use technology that is “untrusted”.
And a Cabinet minister has said the National Security Council will look at the conditions of Chinese tech giant Huawei being involved in the UK’s 5G rollout.
The comments come after it was reported the UK is poised to end the use of Huawei technology in its 5G network as soon as this year, amid security concerns.
Health Secretary Matt Hancock told Sky News: “I wouldn’t comment on leaks of that kind.
“What I can so though, is that when we came out with an interim report on this earlier in the year, there were a number of conditions that needed to be met.
“So I’m sure that the National Security Council will look at those conditions and make the right decision on this to make sure that we have both a very strong telecoms infrastructure… but also that it is secure.
“We have been looking very closely at this.”
The Prime Minister’s decision to allow Huawei a limited roll in Britain’s 5G network is believed to have caused tension between London and Washington DC in recent months.
A report by GCHQ’s National Cyber Security Centre has decided the US sanctions barring Huawei from using technology relying on American intellectual property has had a “severe” impact on the firm, the Sunday Telegraph reported.
The newspaper stated that officials are crafting proposals to prevent new Huawei equipment being installed in the 5G network in as little as six months.
The involvement of the Chinese tech firm in Britain’s 5G network also caused concern among a number of prominent figures on the Conservative backbenches.
The Mail on Sunday reported that the National Cyber Security Centre was instructed to carry out a review on the situation.
It also reported the organisation found that US sanctions had a major impact on the firm’s viability, the newspaper said.
