The EU willWho will?
The US will
China will
Not the UK
Trade negotiations work on reciprocity.
Eg: The UK want fishing because it has ppolitical importance, the EU may say 'nah, if you want fishing, you cant have services, we will restrict passporting rights, creating nudge factors to transfer banking to Europe'
Or Spain will say: 'you want fishing, give us Gibraltar.
The US will say: 'you want access to our services, we want NHS drugs.
Post brexit the UK will be a medium sized economy and it will be in a rather desperate situation of having no FTA deals anywhere.
Japan, Australia, NZ US etc have already said they want a quick deal, because whilst the UK has no deals it is weak, so they want to enter negotiations knowing the UK will capitulate to their demands to seal a quick deal.
