I will give way to the hon. Lady in just a second.
More than that, if we were to publish impact assessments on every single one of these areas, we would be falling prey to a fallacy that politicians and other officials often fall prey to, which is imagining that the diligent work of our excellent civil servants can somehow predict the future—a future in which there are so many branching histories, so many contingent events and so many unknowns. If we produce an impact assessment on leaving the European Union Agency for Railways, how do we know how leaving that agency might be impacted by the enlightened proposals being brought forward by my right hon. Friend the Transport Secretary for the more effective unification and cohesion of our transport network? We cannot know, unless we have that fact in play, but we do not yet know—quite rightly, because he is taking time to consult and deliberate—what that policy will be. What we would be doing is commissioning the policy equivalent of a pig in a poke. With that, I am very happy to give way to the hon. Gentleman.
