Downing Street declined to comment. Huawei
did not immediately respond to a request for comment.
Earlier on Friday, The Times had reported that Johnson had instructed civil servants to make plans to end Britain's reliance on China for vital medical supplies and other strategic imports.
Beijing is being criticised for its handling of the coronavirus
outbreak, which began in China. Beijing denies US allegations it has not been transparent about the outbreak.
"He (Johnson) still wants a relationship with China but the Huawei
deal is going to be significantly scaled back. Officials have been instructed to come up with a plan to reduce Huawei's involvement as quickly as possible," a source was quoted by the Telegraph as saying.
The development would be a change of direction for Britain, which in late April confirmed it would allow Huawei to have a role in building its 5G phone network.
Britain decided in January to allow Huawei into what the government said were non-sensitive parts of the network, capping its involvement at 35 per cent.
The United States has raised security concerns about Huawei equipment, and warned that allies that use it in their networks risked being cut off from valuable intelligence sharing feeds.
