It appears that the UK has arrested a parliamentary researcher and accused him of being a Chinese spy in order to manufacture consent for pressuring the current UK government to be more hostile towards China. https://www.channelnewsasia.com/world/uk-suspect-denies-being-chinese-spy-beijing-slams-claims-3762371<The spying claims, first disclosed in The Sunday Times, are putting pressure on Sunak's government to toughen its policy on China as it seeks greater engagement with the Asian superpower.
I'm assuming Chinese spies are indeed trying to infiltrate the UK government and the reverse is also likely. That's to be expected from inter-state competition. But i don't believe that UK counter intelligence would make a public fuzz about uncovering a spy. If you catch a spy, you try to exploit the situation to feed you're opponent bogus information.
I wonder if that researcher was just some unlucky rando who got sacrificed for a political stunt, or whether they're purging that guy for political reasons. Like was he promoting a insufficiently hostile china stance or something ?
Any anons knowledgeable about the UK, or care to speculate about the spy biz.
