In his first interview of the new year with BBC Breakfast, Boris Johnson stressed he would not put UK security at risk in upgrading the country's 5G network. Johnson is expected to make his final decision on whether to allow the Chinese technology firm Huawei to operate 'non-core' parts of the UK telecoms system within weeks, and said critics of the firm must come up with an 'alternative' provider.



The US has repeatedly warned the UK that allowing Huawei to operate its 5G network could put transatlantic intelligence-sharing at risk.
