Balanced News: Intelligence services set to unmask China spies

British intelligence services are preparing to uncover Chinese spies operating in Westminster, following the arrest of a parliamentary researcher suspected of spying for China. The researcher, who has worked with senior Conservative MPs, was arrested in March alongside another man. The security services suspect that a network of Chinese agents is operating in Westminster and plan to use the National Security Act to detain them. The arrests have raised questions about the vetting process for parliamentary passes, and there are calls for a tougher stance on Beijing, including sanctions or expulsions from the Chinese embassy.
