Fair enough, I accept that the official position of the UK is fragmented at the moment. However, only the most idiotic of leavers or remainers would turn that down, and it's that type of trade agreement that represents a reasonable option for both parties.
After the melodrama finally comes to an end, I expect the EU and the UK to see sense and agree a similar deal to CETA. Both parties win. Britain regains its sovereignty.
But CETA isn't possible without border checks - something the UK government has said it won't do in Northern Ireland?
Also the CETA includes a ‘most favoured nation’ (MFN) clause in chapter 8 on investment, as well as chapter 9 on cross-border provision of services and chapter 13 on financial services.
This means that any offer the EU makes to the UK that is better, in terms of market access, than what the EU has granted to Canada, must automatically be extended to Canada.
Other EU FTAs also include MFN clauses.
So if the CETA model were followed, it would also mean that for the chapters covered, any better access granted by the UK to a third country would also be automatically extended to the EU.
In other words the inclusion of MFN clauses in chapters of FTAs already negotiated by the EU reduces the willingness of the EU to make concessions to the UK.
On the flip side an EU–UK FTA based on CETA would also effectively limit the UK’s options in trade policy, because it would restrict what it could offer, for example to the US or Australia in an FTA.
