He said: "BT takes a risk-management approach on the use of components from Huawei and, like the UK government, we see no need to change our position following the US Report. We work closely with Huawei on commercial security best practice and our relationship with Huawei is managed strictly in accordance with UK laws.

"BT's network is underpinned by robust security controls and built-in resilience. We always work closely with each of our suppliers - and Government where appropriate - to gain assurance through rigorous review that the security of the network is not compromised."Huawei was contacted for a statement but had not responded at time of publication.
