Trade Bill

Can my noble friend clarify the point about services and goods? I asked whether we would be able to continue to do deals on services if we had a tight agreement—a customs union or whatever —with the EU. He was saying that goods and services tend to be linked in trade agreements and are never separate. Would that mean that we could not have services agreements, assuming we got something quite tight on goods? That would obviously be a problem. I know that they are linked—often, the service for your car and the computer in it are as important as the car itself—but I had seen them as distinct in the WTO. If my noble friend could write to me on that, I would be very interested.
