The arrest of a parliamentary staffer suspected of spying for China has sparked calls for a review of those allowed access to the House of Commons.

Former Tory minister Rory Stewart said he was “very worried” about how parliamentary passes are allocated, while justice secretary Alex Chalk promised “lessons will be learned” by the authorities responsible for giving them out.

Despite rigorous vetting of those handed passes to the commons estate, the researcher worked with MPs on international policy, including relations with Beijing, for several years, according to the Sunday Times.
