MI5 director general Sir Ken McCallum apologised to IPCO, after the BBC challenged the Security Service's false statements to the courts. Keeping X's status officially secret meant that key evidence was withheld from Beth. It reviewed MI5 documents about the case of agent X, including an official record authorising a departure from NCND, and sent a draft report to MI5 in February 2023. The report concluded that MI5 had taken the "extraordinary" decision to depart from NCND on X's agent status in calls with me. When contacted by the BBC, IPCO said it was "misled into amending our draft report to remove the finding that Agent X's status had been disclosed."
