Re: Basque complication
The two regions are separate.
The problem is central government doesn't want greater autonomy for either region because the other one will want it too.
In that respect the Basque Country has a little more fiscal autonomy, it collects and passes the money to Madrid whereas Catalonia gets the money collected by Madrid and is then given its share. Catalonia has been trying to get the same deal for years but is told they can't have it.
If Catalonia does actually get independence (doubtful this time aroubd), that immediately will cause a problem with Basque Country because some there will want independence too.
