Asked about Collins, the deputy national security advisor who submitted the witness statements to the CPS, McCallum said he would make a “rare exception” to speak about Collins’ integrity, having worked with him. “I do consider him to be a man of high integrity and a professional of considerable quality,” he said.
McCallum was also careful not to criticize the work of the CPS, telling journalists: “Not only am I not a criminal prosecutor, I’m not a lawyer. And so for the same reason that the DPP (Director of Public Prosecutions) presumably wouldn’t stand up and comment on how to run covert intelligence operations, I’m not going to presume to appoint myself a temporary expert in the running of prosecutions.”
The decision to replace Britain’s Official Secrets Act with a new National Security Act — pointed to by the current Labour government as a key reason the case collapsed — was praised by McCallum, who said it has “definitely has closed serious weaknesses that we have previously suffered from.”
China a wider threat
The MI5 head said the relationship between Britain and China is “complex,” but his agency’s role “is not,” adding that the U.K, needs to become a “hard target” to “all the threats, including China, but not limited to China.”
McCallum revealed that in the last week MI5 had “intervened operationally” against China, though this is not believed to be related to alleged spying on Parliament by Beijing.
“Do Chinese state actors present a U.K. national security threat? And the answer is, of course, yes they do, every day,” he said. However, the MI5 chief would not “comment on the overall balance of U.K. bilateral foreign policy relationships with China.”
“When it comes to China the U.K. needs to defend itself resolutely against security threats and seize the opportunities that demonstrably serve our nation,” he added, pointing that the U.K. and its Five Eyes allies including the U.S. share a “pragmatic approach” and that having a “substantive relationship with China” means Britain is in a “stronger position from which to push back.”
