A committee of MPs challenged the existing system of oversight for the security services by asking the head of MI5 to justify his claims that the Guardian has endangered national security by publishing leaks from the former NSA contractor Edward Snowden.
In an unprecedented step, Keith Vaz, the chairman of the home affairs select committee, announced that spy chief Andrew Parker had been summoned to give evidence in public to the Commons committee next week.
Labour committee member David Winnick also pointedly ridiculed the ISC referring to the way in which Britain’s three main spy chiefs had been given prior notice of the questions in its first public evidence session last month. Some committee members want Parker to reveal how much MI6 and MI5 had told the ISC about its mass programme of surveillance, so in effect testing the value of the ISC as a constitutional check on the security services.
It should be an interesting appearance.
