Dr Julian Lewis: Will the Leader of the House try to find time for the Deputy Prime Minister to come to the House next week to make a statement about the transport industry? London Underground has yet to receive any significant capital investment, whereas Railtrack has today announced an investment of no less than £27 billion of private capital. That is a remarkable contrast, and the House should hear about it from the Deputy Prime Minister when he chooses how he wants to proceed with the future of London Underground.
