Professor Tamara Hervey:

In the short term, the relative costs of reducing reliance on the UK are likely to be significant, but one might want some modelling of what they will be in the longer term. Given that there can be a route between ports in, say, Spain and Ireland, can there in the medium term be a complete bypassing of Great Britain? It is slightly uncomfortable for me to advise that my country should be cut out of global trade but, unfortunately, that is the political position of my country.
