Ten Conservative lawmakers sent a letter to Johnson demanding that he remove Huawei from the UK's critical national infrastructure.
Johnson in January sought to balance economic and security pressures by agreeing to give Huawei a limited role in Britain's so-called 5G network, excluding the company from core components of the system and restricting its involvement to 35% of the overall project.
But the move set up a diplomatic clash with the Americans, who threatened to cut off security cooperation unless Britain dumped Huawei. Amid continued pressure to remove Huawei from communication networks entirely, the US in May imposed new sanctions that will bar companies around the world from using American-made machinery or software to produce chips for the Chinese company.
