Prime Minister Boris Johnson says that any decision on whether Huawei will be allowed to build parts of the UK’s 5G infrastructure will not happen until after the election on 12 December.
Mr Johnson said: “On Huawei and 5G, I don’t want this country to be unnecessarily hostile to investment from overseas.
“On the other hand, we cannot prejudice our vital national security interests, nor can we prejudice our ability to co-operate with other Five Eyes security partners.”
The UK, the US, Canada, New Zealand and Australia make up the Five Eyes group – the international intelligence network formed after World War Two.
Mr Johnson and US President Donald Trump discussed the issue during the Nato summit in London.
A spokesman for Huawei told The Times: “We’re confident the UK government will continue to take an objective, evidence-based approach to cybersecurity. Our customers trust us because we supply the kind of secure, resilient systems called for by the Nato declaration.”
