> We must remember that Catalonia has already held two legal referendums, where the result has been a refusal of the Catalan people to leave Spain or Independence

That's not true, I think you are confusing Catalonia with Scotland.

Preciselly one of the main issues is that a part o Catalonian society (I would say a big one, from both sides, independentist and non independentists) wants a referndum, but Spain refuses to do it.
