An alleged Chinese spy who forged a close relationship with Prince Andrew has been identified by a British court, the latest twist in a case that has shone a light on Beijing’s influence inside Britain’s institutions.

The story has attracted attention as evidence of a potential national security threat from China and as another scandal that involves the prince’s relationships.

An alleged Chinese spy who cultivated close ties with Prince Andrew said Monday he has done “nothing wrong or unlawful” as Britain’s government faces questions about what it is doing to thwart security threats from China.
