UK-EU Trade would only remain a mess if the EU non negotiated schedule to March 2019, continues to put unreasonable ‘Round 1’ demands on the UK, and the more fundamental mutual prosperity of future Trade, last on the agenda.
The UK as a mainly ‘Services’ economy, and the City here is already assuming no ‘passporting’ rights to do financial services business with the EU from London (so moving on average around 20% of their total business that is EU related, to Europe), one would assume that IF the EU is commercially orientated – that an EU that sells far, far more solid ‘stuff’, and of a much higher net cash value TO the UK – would get their ‘stuff together on Trade a lot earlier, as WHAT would the UK be paying a divorce bill premium, for?
If European businesses don’t want to speak up on their own commercial behalf, then so be it, WTO is the only option, and ‘the man from……the WTO’ doesn’t seem to think it will be major problem for parties of good-will – but that’s the problem of a UK-EU trade agreement in the first place e.g. the bottom wipes on the OTHER side, trying to extort tens of Euro billions cash, without the basic respect of a detailed invoice.
