Question to the Cabinet Office:
To ask the Minister for the Cabinet Office, pursuant to the Answer of 8 May 2019 to Question 250002, how many and what proportion of UK 5G operators (a) use and (b) do not use the Huawei Cyber Security Evaluation Centre advice.
The annual report generated by the Huawei Cyber Security Evaluation Centre (HCSEC) Oversight Board which includes communication service provider representatives is publicly available. We do not track how many operators use Huawei Cyber Security Evaluation Centre advice.
It remains the responsibility of operators to ensure the security and resilience of their networks, based on all the available advice from both Government and the private sector. Ofcom are the regulator for the telecoms industry and consider whether operators are meeting their responsibilities and investigate as appropriate.
