Transport committee: the cost of Crossrail

With blissful timing, the Assembly's transport committee will this morning make reference to its report of March last year on London's response to extreme weather conditions - that's assuming the snow doesn't stop members getting to City Hall, of course. The main event, though, will be the cross-examining of Crossrail bosses about costs. Mayor Johnson says this will be "a huge year" for the project. His good friend Lord Adonis thinks it will be marvelous . Simon Jenkins doesn't . Watch a webcast of the transport committee from 10:00 via here . Update, 15:08 Jenny Jones on Crossrail and the environment .
