The Chinese embassy has told the UK to “stop creating trouble”, after a businessman accused of being a spy for China was banned from the country.

The revelations about Yang Tengbo, who denies wrongdoing, and his links to Prince Andrew, have sparked renewed calls for the UK to designate China a threat to national security.

The issue poses a dilemma for the government, which is hoping to strengthen ties with China to help boost economic growth and tackle shared issues like climate change.
