Today is an important day. It is a day some of Gordon Brown's chickens will come home to roost. My friend Christian Wolmar tells me that Metronet are going to be knocking on Mayor Livingstone's door this morning and saying "sorry, but we can't run these undergound contracts and we will have to go into administration"
The maintenance and refurbishment of two thirds of the tube lines (9 out of 12) now lie in tatters. No doubt the poor bloody taxpayer will be called on again, but this is a huge embarrassment for Gordon Brown as the whole scheme was his idea in the first place. He was warned by experts at the time that these were unworkable and too complex (they cost £500 million to draw up) but he went ahead anyway.
It is now time for the National Audit Office to launch a full scale inquiry into these contracts and how Metronet has failed to control costs. Witness number one should be the First Lord of the Treasury.
