I have just heard the Rt Hon Michael Mates MP talking eminent sense of Radio 4’s World Tonight (he’s about 30 minutes in). He is a member of the Intelligence and Security Committee (the Parliamentary Committee that oversees the Security Service and whose report “Could 7/7 have been prevented?” is published today). His comments were measured and dispassionate. They didn’t treat national security questions as a political football or an occasion for political point-scoring. He was being statesmanlike and behaving responsibly – exactly what I suspect most members of the public would like to get from their MPs.
