Do trade policies have to change after Brexit? Being part of the EU is surely not the only way to participate in a free trade market. Could the UK continue with the same policies despite not being part of the EU?
The UK do it the "Norway way" this would mean they are part of the
European Economic Area, they need to pay into EU budget (roughly 80% of current pay) but
have no Seat in Brussels)
The Switzerland way - bilateral deals and roughly 50% of the
Norway way costs.
Lone Member of WTO.


In any way, Britain would gain the freedom to make its own trade deals (how about TTIP?!).
