At the heart of the debate is a simple question: can the West trust Huawei or will using its equipment leave communication networks, and our own mobile phones, vulnerable?

The US says Huawei could be used by China for spying, via its 5G equipment. It points to Mr Ren's military background and Huawei's role in comms networks to argue it represents a security risk.
That Pompeo chap was throwing his considerable weight around Whitehall earlier, saying the British should refuse to allow any Huawei hardware to be attached to the UK's phone network on security grounds. We cannot trust the Chinese not to spy on the traffic or interfere with it, he said.

The man is a rogue speaking on behalf of rogues running a rogue nation.

Which country has actually infiltrated most spying hardware worldwide for generations? China? Russia? North Korea? Nothing of the sort.

Has nobody red anything Edward Snowden published? Does nobody believe he was accurate?

It's the wretched Americans who do it regularly, consistently, predictably, to everyone. Including Americans themselves, of course.

And what country's hardware would Mr Pompeo want in the UK 5G network? You don't even have to ask, you already know.

I'd much rather have Huawei, thank you very much. They're more trustworthy.

Switzerland is probing news reports that the US Central Intelligence Agency and West Germany’s spy service used a Swiss company’s encryption technology to covertly crack other nations’ top-secret messages, the Swiss defence ministry said today.

The company, called Crypto AG, sold code-making equipment to Iran, Latin American nations, India, Pakistan and dozens of other countries. The technology was modified to let the CIA and Germany’s BND break codes, the Washington Post reported along with German and Swiss broadcasters ZDF and SRF.

The reports cite a classified CIA history to underpin the allegations, some of which date back at least to 1992, when one of Crypto’s employees was arrested and held in Iran for nine months as a suspected spy.

At the time, the company called reports that it was a secret asset of Western intelligence agencies “an unbelievable conspiracy theory,” according to a report in German magazine Focus detailing a 1994 book on the subject.
