Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, pursuant to the Answer of 5 June 2019 to Question 257533 on Huawei: 5G, what recent assessment he has made of the risks to the (a) security and (b) reliability of UK 5G networks from Huawei Cyber Security Evaluation Centre evaluating 5G equipment after deployment.

As detailed in the HCSEC Oversight Board report, the HCSEC work programme is
determined by a risk-based prioritisation scheme and their plan of evaluation is driven by
the commercial rollout of services by the UK operators that use Huawei equipment. The
operators, NCSC and the HCSEC collaboratively prioritise the work of HCSEC. Providing
further details on what equipment has, and has not, been subject to HCSEC evaluation is
commercially sensitive.
