Does the Minister agree that the concept that I have presented to him, along with the hon. Member for Romford (Sir M. Neubert) and the Transport on Water Association, has the advantage over the London First scheme in that it would be integrated with the transport network and would not result in tourists paying £5 or £10 a go? The Minister has received the correspondence and should be aware that no fewer than 10 piers could be constructed between Vauxhall and the Tower for a third of the cost of the London First proposals, and that those could be used not only by passenger services but by other vessels. Would not such a public investment be good value for money compared with the £80 million to £100 million being spent on two platforms of the Jubilee line—albeit, of course, that that could interchange with passenger services such as I have described?
