London Underground

Does the hon. Gentleman agree with my right hon. Friend the Member for Greenwich and Woolwich (Mr. Raynsford) that no lessons need to be learned about the supervision of the Tube Lines contract from this spectacular collapse, although the company's only exposure is the £180 million of equity it has invested in the project and although, four years into a 30-year project, it has already made a ““profit”” of nearly £160 million? That is not much of an exposure to risk, is it?
