"Nothing has changed." That's what journalists have been told each and every day when we have asked whether the prime minister has been interviewed by the police.
At this morning's Lobby briefing, a grim-faced Tom Kelly - the prime minister's official spokesman - revealed that, in fact, Tony Blair was questioned as a witness by police for the second time last Friday morning.
Had Kelly misled us? He insisted that he and the entire Number Ten media team were themselves unaware of this news until late yesterday, and therefore he had never knowingly misled journalists. The interview had been kept secret, he said, at the specific request of the Metropolitan Police. We await a statement from them with interest.
