Extraordinary. Gob-smackingly spine-chillingly hair-raisingly extraordinary.
Tony Blair planned to say nothing as he left Downing Street for the last time, but his carefully laid plans were once again torn up by his wife. As Mrs Blair got into the Jaguar to leave Downing Street for the last time, she looked directly into the cameras just feet away from her and spoke - not whispered, not mouthed - the following: "Goodbye. I don't think we'll miss you" (watch for yourself here).
Now that's an end to suggestions that Tony Blair is leaving entirely at a time of his own choosing (though he did choose the day and wishing all well as he did so).
One more thing. Earlier when I bumped into Mrs Blair and three of her four children as they were waiting in Parliament's central lobby to be escorted to the public gallery to watch prime minister's questions, I said to one of her children: "I hope you enjoy the day." They smiled. She looked at me with daggers.
CLARIFICATION 1600 BST: When earlier I wrote that this was "an end to suggestions that Tony Blair is leaving entirely at a time of his own choosing", I seem to have provoked some consternation.
Let me explain what I meant. The attempted coup last autumn DID force Tony Blair to promise to leave office before he wanted although he was nevertheless able to choose the precise date on which he left. Cherie Blair is angry with Gordon Brown for those events and with the media for the way she perceives they attacked her and her husband.
