Parliament’s Intelligence and Security Committee (ISC) – not a select committee, but a group of senior MPs and Peers appointed by the PM – has a “canary in the coalmine” function, to keep an eye on the security and intelligence services and reassure Westminster that all is well. But last week the canary emitted a loud squawk. The ISC raised concerns about its secretariat being under-funded and too tightly controlled by the Cabinet Office – issues that could hinder its independence and effectiveness.
