Question to the Department for Digital, Culture, Media & Sport:

To ask Her Majesty's Government what plans they have, if any, to review Huawei's planned involvement in the UK's 5G network.

The Government conducted a comprehensive, evidence-based review into the telecoms supply chain, which was published in July 2019. The final conclusions of the Government’s Telecoms Supply Chain Review in relation to high risk vendors were announced on 28 January and provided the details of the additional steps it will be necessary to take to mitigate the risk from high risk vendors. This announcement made clear the Government’s intention to, over time, reduce our reliance on high risk vendors as market diversification takes place. We want to get to a position where we do not have to use a high risk vendor in our telecoms networks at all.

The conclusions of the Review were based on security analysis from our world-leading cybersecurity experts, and took into account the full range of issues and risks.
