Robert Hannigan was Head of GCHQ, Britain’s equal of the U.S. NSA. Before that, he was the Prime Minister’s Security Adviser. England and the U.S. work together on security so he probably knows more about the spy stuff than anyone else in Europe.
In the Financial Times, Hannigan just wrote “Blanket Bans on Chinese Tech Companies Like Huawei Make No Sense” R| Feb. 12, 2019
“The UK National Cyber Security Centre has never found evidence of malicious Chinese state cyber activity through Huawei.” He was in charge.
Hannigan adds, “In assessing what the actual risk from Chinese tech may be, the UK has a unique advantage. The GCHQ-vetted facility, which has been evaluating Huawei’s presence in UK telecom networks for some years, has given us a detailed insight into the company’s hardware, code, processes and policies. …
Assertions that any Chinese technology in any part of a 5G network represents an unacceptable risk are nonsense.”
No one except the heads of the US NSA & CIA knows more than Hannigan.
