The security and resilience of the United Kingdom’s telecoms networks is of paramount importance. The UK has one of the world’s largest and most dynamic economies, and we welcome open trade and inward investment in our digital sectors, but at the same time the UK’s economy can only prosper when we and our international partners are assured that our critical national infrastructure remains safe and secure.
As part of our plans to provide world-class digital connectivity, including 5G, my Department has been carrying out a cross-Whitehall evidence-based review of the supply chain to ensure a diverse and secure supply base. The review aims to ensure stronger cyber-security across the entire telecommunications sector, greater resilience in telecommunications networks and diversity across the entire 5G supply chain. It has considered the full UK market position, including economic prosperity, corporate and consumer effects and the quality, resilience and security of equipment.
Despite the inevitable focus on Huawei, the review is not solely about one company or even one country. We have to strike a difficult balance between security and prosperity, and recognise the reality of globalised networks and supply chains, although I will make it clear that our security interests are pre-eminent and that has been the focus of this review. That is the way to ensure that the UK fully realises the potential of 5G through its safe and secure deployment.
As would be expected given the importance of the subject, it is a thorough review of a complex area, which has made use of the best available expert advice and evidence, including from the National Cyber Security Centre. It will report with its conclusions once ministerial decisions have been taken. The review is an important step in strengthening the UK’s security framework for telecoms and ensuring the secure roll-out of 5G and full-fibre networks.
I am sure that the House will understand that National Security Council discussions should be confidential, and will understand why that must be the case. However, I know that Members on both side of the House feel strongly on this issue and I will make a statement to the House to communicate final decisions at the appropriate time.
