LEADING MPs are to probe the collapsed “China spy” case after a week of Westminster accusations and rhetoric about the issue.

The joint committee on national security, including the chairs of the Commons home affairs, foreign affairs and justice committees will conduct the inquiry.

The move was announced after the publication of the evidence submitted by the government in the case predictably failed to still the row.

Tories have been trying to pin the blame for the failure to prosecute two men for allegedly spying for China on the government.

Prime Minister Sir Keir Starmer has said the problem was caused by the last Tory government not formally designating China a “threat” to Britain.

He told Tory leader Kemi Badenoch that he was disappointed the case did not proceed and that the decision was made solely by the Crown Prosecution Service (CPS) without government interference.

Both men have denied any wrongdoing and assert their innocence.
