How the fuck can be a link of the ICV, they are not left, they are just social democrats, the catalonian brand of IU. And by the way they are not independentist either.
Even so, national self-determination is a cornerstone of leftism.
Not for the main part of the Spanish Left, they have the 10.000 km law, any national liberation struggle abroad should be supported if it's within Spain fuck them all.
