Digital Secretary Oliver Dowden said:
"5G will be transformative for our country, but only if we have confidence in the security and resilience of the infrastructure it is built upon."
"Following US sanctions against Huawei and updated technical advice from our cyber experts, the government has decided it is necessary to ban Huawei from our 5G networks."
"No new kit is to be added from January 2021, and UK 5G networks will be Huawei free by the end of 2027. This decisive move provides the industry with the clarity and certainty it needs to get on with delivering 5G across the UK."
"We are already working with all our Five Eyes partners on those alternatives," Dowden told parliament, referring to cooperation between the group of allies comprising the US, Britain, Canada, Australia and New Zealand.
"The first thing we need to do is ensure that we protect the other two vendors in this market so Nokia, and Ericsson. Secondly we need to get new suppliers in, that starts with Samsung, and it starts with NEC," he said.
"This disappointing decision is bad news for anyone in the UK with a mobile phone. It threatens to move Britain into the digital slow lane, push up bills and deepen the digital divide. Instead of 'levelling up' the government is levelling down and we urge them to reconsider. We remain confident that the new US restrictions would not have affected the resilience or security of the products we supply to the UK.
"Regrettably our future in the UK has become politicized, this is about US trade policy and not security. Over the past 20 years, Huawei has focused on building a better connected UK. As a responsible business, we will continue to support our customers as we have always done.
"We will conduct a detailed review of what today's announcement means for our business here and will work with the UK government to explain how we can continue to contribute to a better connected Britain."
