Clare Short's resignation from the Labour Party today is not just the culmination of a long process of personal disillusionment with the party, but the latest example of Tony Blair's failure to retain the trust of the people who once constituted his top team.
Short is the second member of the 1997 Labour Cabinet to leave the party, the first being ace badger-watcher Ron Davies. I cannot recall this ever happening to another Government in my lifetime, although others may have longer memories....
Of that initial Blair Cabinet, just six members remain - the Prime Minister himself, John Prescott, Gordon Brown, Jack Straw, Margaret Beckett and Alastair Darling, great political survivors all.
Four are dead - Ivor Richard, Donald Dewar, Robin Cook and Mo Mowlam - while another five - Ann Taylor, Jack Cunningham, David Clark, Chris Smith and George Robertson - have joined Derrry Irvine in the land of the living dead, aka the House of Lords.
Oct 23 Update: Rumours of Ivor Richard's death are apparently greatly exaggerated - see comments thread below.
