I am grateful to my hon. Friend's comments on my visit to Greenford. I am sure that he will be the first on the telephone if the escalator is not working at the station. My right hon. Friend the Secretary of State for Trade and Industry must decide when to publish the report of the Monopolies and Mergers Commission. Investment in the underground, excluding the Jubilee line and the east-west crossrail, is around £400 million per annum. There is certainly justification for increasing that amount. During the coming public expenditure round, my right hon. and learned Friend the Secretary of State for Transport will seriously consider what needs to be done.
