Trade union militancy is clearly back in vogue. Bob Crow, leader of the RMT Tube union, is no Islington Blairite. He is a classic canteen demagogue. The same goes for Mick Rix of the train drivers and Derek Simpson, about to topple Tony Blair's friend, Sir Ken Jackson, as leader of the engineers. Round at the TGWU, the statesmanlike Bill Morris is about to give way to the Left-wing Tony Woodley. In addition, today comes news that the TUC is threatening to cut its links with Labour and is demanding the biggest extension of workers' power in a generation.
