Like most people of my age, I clearly remember where I was when Margaret Thatcher went. Actually the answer was on a train between Derby and London on my way to a job interview. A woman got on at Leicester shortly after 9.30am and told the carriage "she's gone." I could hardly conceal my glee and managed to get into a row with someone on the seat opposite who clearly thought it was the worst disaster to hit the country since Dunkirk.
Will I remember in 17 years' time where I was when Tony Blair announced his resignation today? I doubt it.
Like Iain Dale I don't think this was one of Tony's best efforts. It seemed to me as if the Great Communicator had said all he really needed to say in his party conference valedictory address last autumn and was flailing around vainly in search of a new line.
In the end, the best he could come up with was "I did what I thought was right for our country." Which, I suppose, has the merit of humility if not that of startling originality.
In common with some other bloggers, I do eventually plan to have a celebratory beer to mark Blair's departure, and to drink a toast to the memory of Dr David Kelly who was driven to take his life by the activities of this wretched regime and for whom today's events represent some sort of delayed justice.
However since Blair is still in No 10, I suppose this small commemoration should wait until 27 June - the day the Blair era will finally come to an end.
