If every vote from separatist parties is needed for the continuum of the government, how long would it last?
Also, could the political right win an absolute majority in the foreseeable future?
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
The separatist parties could further see their support eroded in this way...
OT: if Sanchez managed to cling on, I could foresee a way of Trudeau hanging on after next Canadian election, on the condition of CPC getting less than 170 seats. Negotiations between LPC, NDP and BQ is theoretically easier than that between PSOE and ERC/Junts.
If this is set as precedent, the only way of CPC winning government in next election is them getting an absolute majority of seats.
