The head of MI5, the UK’s domestic security service, revealed that its spies had disrupted a new threat from China in recent days, as he expressed frustration over the collapse of a espionage case linked to Beijing.
“We’ve intervened operationally again just in the last week,” MI5 Director-General Ken McCallum told reporters on Thursday, declining to elaborate on the nature of the activity. “Do Chinese state actors present a UK national security threat? The answer is: Of course, yes, they do — every day.”
