Speaker Hoyle discussed the situation with his European counterpart to learn how such restrictions could be practically imposed in the U.K., the Telegraph reported. Hoyle’s office did not respond immediately to a request for comment.

The move comes amid intense scrutiny of Prime Minister Keir Starmer’s government and the Crown Prosecution Service after charges against two men — including a former researcher for a Conservative MP — accused of spying for China were dropped.

It’s not the first time Hoyle has flexed his muscles on China. Beijing’s Ambassador to the U.K. Zheng Zeguang was banned from parliament in 2021 in retaliation for China imposing sanctions on British MPs critical of the country’s human rights record.
