Timely? It could easily have been the same actor.

Given that the spying on catalan independentists started under the previous government (right wing, strongly centralist), I wouldn't discard it extended subsequently to the current one (coalition of left wing and extreme left, some of which friendly to catalan nationalists). It remains to be seen if the analysis they are conducting now reveals other members of the government who have been spied too.

I guess this could come from the previous government, rogue elements of the state, or an international actor, but I wonder if we wil be told when and if it is found out.
