Pompeo raises pressure over Huawei before May meets Trump

Next PM could overturn decision to let Chinese firm supply non-core 5G kit

Mike Pompeo, the US secretary of state, has ramped up the pressure over the use of Huawei technology in 5G networks hours before Donald Trump was expected to demand that the UK rethinks its plan to do business with the Chinese company.

The US president is due to meet Theresa May in Downing Street on Tuesday. There is growing speculation that her successor as prime minister could overturn her decision on Huawei.
