It's actual until recently been a bit redundant as Wales was only really created as a recognisable entity as it was annexed to England (thus becoming part of England as any other county or region, Yorkshire for example).
I've not really researched if Wales exists as a country now only that someone told me the laws establishing the Senedd and giving it powers had changed the situation.
If we're being pedantic shouldn't it be England-and-Wales libel law?
