espionage

The London office where much of “The Agency” takes place captures the contradictions of this contemporary espionage drama.

Beijing has always denied all accusations of espionage.

His research often embarrassed the authorities, who were forced to admit that some of the shady tactics he revealed were used in real-life espionage.

Ken McCallum, MI5 director general, meanwhile, has previously warned of a sustained campaign on an "epic scale" of Chinese espionage abroad.

Meanwhile, China is a "sophisticated and persistent challenge", the review warns, and is "likely to continue seeking advantage through espionage and cyber attacks" and is expected to have 1,000 nuclear warheads by 2030.
