The Government has announced it does not trust the Chinese telecoms company Huawei to make equipment for Britain’s 5G network.
It has banned UK telecoms companies from buying new kit from Huawei and told them to strip it from their 5G network over the next seven years.
The move will cost billions and delay the roll out of the new and faster mobile data system by up to three years.
It is a sharp u-turn from the decision announced just six months ago to let Huawei make up to a third of the 5G network.
China’s Ambassador to the UK said the decision was disappointing and wrong.
