BT and Vodafone told to stock up on Huawei kit over US sanctions

Security officials fear UK telcos could run out of vital parts if US pressure disrupts supplies

British security officials have told telecoms operators to ensure they have adequate stockpiles of Huawei equipment owing to fears that US sanctions will disrupt the Chinese firm's ability to maintain critical supplies, according to a letter seen by Reuters.

Senior officials at the National Cyber Security Centre (NCSC), who are studying the impact of new US measures intended to restrict Huawei's ability to source advanced microchips, wrote to BT and Vodafone last week, said three people familiar with the matter.
