North West England has a lot of experience of working with other European countries in the aerospace and the automotive industry, also the travel industry and many others.
A point made by several politicians is that the EU will be desperate to negotiate a trade deal with the UK if it leaves and this gives us some advantage.
This seems to defy the common expectation that in most deals bigger does better. The EU, US and China are big. The UK is relatively small. In fact the UK has a lot of people who would like to be one up on it. So why will a separate UK will get a good deal off any of these or anyone else? It would be good to know, answers please!
