Catalan political exile Clara Ponsatí has appeared in Paris this week campaigning for election to the European Parliament. This is significant because it had been believed that France would be more likely to allow extradition, but Spain didn't try to issue a Euro arrest warrant.
This could indicate that Spain is not even trying anymore to extradite the exiles, knowing it's futile, or that France is not willing to cooperate with Spain in this way anymore.
