If we are pedantic, CC and BNG, both with a single seat each, can be dropped. That being said, BNG won't ask for much (basically more money for Galicia) and CC's support really seems a last ditch effort to keep the money tap flowing but they have no leverage over Sanchez
Realistically it's going to come down to Puigdemont. And the next Catalan election will have a lot to do with how the Spanish government evolves
Simultaneously, an agreement was reached with the BNG to reduce tolls on two Galician highways (namely AP-9 and AP-53) and the creation of railway connections in Galicia.[153][154]
The best kind of Spanish regionalism. If only Teruel Existe still held a seat in Congress...
