There was a time not that long ago when you knew it was a Labour MP speaking on TV because he wore a red tie. Tories sometimes wore a blue one and Liberals any colour they liked, but for Labour a red tie was mandatory.
This changed with New Labour. They no longer wanted to be reminded of the past, the history of the party. Red stood something. It was the colour of the worker's flag. It was the colour of the blood shed by generations of activists going back to the Chartist and before.
As the various Blairites and Brownites start to creep away from their previous positions I wonder if the red tie will make a comeback. We are now seeing them dump the 'New' and just calling themselves Labour and even the banned word socialism cropped up today, so maybe we will. (And yes Ken Livingstone, I noticed the yellow tie you have been wearing. A little bit of tradition please!)
