On behalf of the Intelligence and Security Committee, I entirely endorse the tributes and good wishes paid by the Solicitor General and the hon. Member for St Helens North (Conor McGinn) to my right hon. Friend the Member for Old Bexley and Sidcup (James Brokenshire). His professionalism, calmness and dedication as Security Minister and in other roles are a model for us all. We admire him greatly and wish him the best of health.
Despite extraordinary technical advances in surveillance and espionage methods, human sources in intelligence operations remain indispensable, especially in the counter-terrorist work of our Security Service. Going undercover to join terrorist groups or remaining in a terrorist group, having become disillusioned with its objectives, in order to frustrate them, calls for courage of the highest order. The Intelligence and Security Committee has been briefed by MI5 on specific instances of this, and we accept that, without the use of covert human intelligence sources, many of the attacks foiled in recent years would have succeeded in their horrific aims. That is what justifies the authorisation of specified criminal acts, on occasion, in order to maintain an agent’s cover and in proportion to the potential harm that he or she is working to prevent.
As pointed out on Second Reading on 5 October, the report on Northern Ireland-related terrorism compiled by our predecessor Committee and presented to Parliament that same day firmly concluded at paragraph 39:
“While there are, rightly, concerns that criminal activity may somehow be being legitimised, the need for such authorisations is clear. What is key is that authorisations are properly circumscribed, used only when necessary and proportionate, and subject to proper scrutiny.”
Precisely because covert human intelligence sources are so effective, ruthless terrorist organisations have no qualms in devising tests of the utmost depravity to flush out agents infiltrating their ranks. That is why the provisions of Lords amendment 2 to prohibit the granting of criminal conduct authorisations, or CCAs, are certain to be as counterproductive as they are well-intentioned.
What the amendment proposes, if enacted, would soon come to constitute a checklist of atrocities that could be used to expose undercover agents known to be forbidden from carrying them out. As sure as night
follows day, it would also increase the number of such atrocities committed. In order to flush out MI5 agents by putting suspects to the test, paranoid extremists would resort to testing more and more of their group members, if they felt that their organisation was coming under pressure and suffering setbacks.
