Why has the UK dropped its trial of two alleged China spies?

The UK has unexpectedly dropped its trial against two alleged spies for China, raising questions about the government's commitment to national security. Stephen Parkinson, the director of public prosecutions, hinted that the decision lacked support from Downing Street, leading to a political uproar. This case involved serious allegations against Britons, including a parliamentary researcher, and its dismissal could undermine public trust in the legal system's ability to handle espionage effectively. The implications of this decision are significant, as it may embolden foreign interference and weaken the UK's stance on national security.
