In a surprise reversal, British Prime Minister Boris Johnson is set to start phasing out the use of Huawei equipment in the 5G infrastructure of Britain this year, The Telegraph disclosed.

GCHQ is believed to have modified its previous pledge that it can safely handle the threats presented by the Chinese technology giant.

A report due to be released this week to the Johnson is seen to conclude that new US restrictions on Huawei will force the group to use questionable technology that could make risk nearly difficult to control.

The prime minister's decision to give the Chinese tech very minimal participation in Britain's 5G landscape has caused friction between Washington and London in recent months.

A document presented by GCHQ's National Cyber Security Center has found the US sanctions that ban Huawei from using technology that relies on American intellectual property has had a major effect on the firm, the Telegraph reported.

The newspaper disclosed regulators are drawing up propositions to keep the latest Huawei technology being set up in the 5G network in as little as six months.

The report comes as the prime minister faces his biggest backbench revolt yet, with Tory members of parliament threatening a parliamentary "rebellion" if the government failed to carry out a tougher approach to Huawei and China.

Earlier last week, Oliver Dowden, the European Union's digital and media secretary, disclosed that the US sanctions will likely have a major impact on the capability of Huawei as a competent provider for the 5G network.

On Tuesday, Johnson said that he is not a "Sinophobe" and that he will not be "drawn into Sinophobia," adding that he does not want to see the region's critical infrastructure "properly protected from hostile state vendors, so we need to strike that balance," Sherisse Pham of CNN Business, wrote.

The Chinese tech firm divulged earlier this year that it has secured 91 commercial 5G deals, with over half (47) in Europe, 27 in Asia, and 17 elsewhere around the globe.

Washington has long viewed Huawei with a lot of caution, doubtful of how closely the group is connected to the Chinese Communist Party. Huawei maintains that it is a private consortium owned and operated by thousands of its personnel.

A Huawei official said the company is the most scrutinized vendor in the world "and we firmly believe our unparalleled transparency in the UK means we can continue to be trusted to play a role in Britain's gigabit upgrade," Edward Malnick of The Telegraph reported, as published on Yahoo.
