Sir Paul Stephenson, in his statement to the London Assembly, has made clear that it was the Serjeant at Arms who gave permission for Damian Green's office to be searched. His message: Don't blame me, I was only doing my job. She in turn may well deflect responsibility onto the Clerk to the House of Commons, Dr Malcolm Jack. The big question, which will hopefully be answered this afternoon, is whether the Speaker was merely informed, or gave his active consent.
Sir Paul carefully avoided the question of whether he or his colleagues told the Serjeant at Arms if the CPS or DPP had endorsed the need for Green's office to be searched. The DPP denies this. Sir Ken MacDonald, the outgoing DPP told Newsnight last night that he would certainly have been expected to be consulted directly.
Sir Paul Stephenson also said that there "could have been national security implications" in this case, but failed to outline what they were. A good deflecting tactic if ever there was one. There are clearly no national security aspects behind the leaks at all.
