The withdrawal agreement does not of itself form part of an economic impact assessment. I think the hon. Gentleman is referring to the political declaration, and there, the Government have published a range of analyses to explain the predicted economic impact of a number of different potential future relationships with the European Union. Because the approach set out in the political declaration is capable of reaching resolution at different points in the spectrum described in that document, we have taken the nearest proxy for it. We have explained our methodology completely, and I think that any reasonable questions that the hon. Gentleman has are answered in the document that the Government have already published.
