On to the putative trade deal.
Clearly the ideal outcome from a UK perspective would be full, tariff free, smooth access to all EEA markets for all our goods and services without the bother of having to worry about EU regulations we don't like and without having to allow FoM of labour, whilst being able to control imports to some extent in order to benefit domestic production.
Obviously we're not going to get that. Customs checks are going to slow things down to some extent, tariffs will be imposed on some exports that we can't negotiate into the deal. No idea how the services market will pan out but I'm sure the major companies will have contingency plans for whatever happens which may include the relocation of some operations outside the UK.
So what would be an equitable outcome? A reduction in EEA trade by 3%, 5% or 10%? I don't think anyone thinks it's going to increase as a result of Brexit.
This is supposed to counterbalanced by increased trade with the rest of the world, which realistically means the US, China, India and the rest of the commonwealth that's not already in a deal with the EU. The other major markets already have deals with the EU that we benefit from. We already have trade trade surpluses with the US and India so they are not going to do us any favours in a trade deal. For the US we would doubtless have to accept increased US access to health care and agriculture if we want more access to their markets. For India, the quid pro quo is likely to be freer movement of people to the UK.
What would be a good outcome by the end of the year?
