My hon. Friend is making a powerful case. As he will know, my hon. Friend Jim Fitzpatrick and I have concerns about the Enderby Wharf cruise liner terminal that is planned for East Greenwich. In that instance, the developer is saying that the cruise liner company with which it is working does not have the necessary technology. Is there not a role for the Government here? Could they not regulate to encourage cruise liner companies to upgrade and retrofit their fleets so that they can utilise this option when ports and terminals take it up?
