We recognise the potential benefits of free ports generally, but there are practical challenges, which is what I was referring to in my earlier response, I think, which is around loss of tax revenue, displacement, sustainability, and so on. Decisions on free ports and customs arrangements more generally, obviously, are in the hands of the UK Government. From our point of view, the economic interest of our ports and of our economy at large is best protected by remaining part of a customs union, and if that comes at the cost of being able to develop particular free port discussions, then I think that is a price worth paying in the overall picture in terms of the overall impact on our economy.
