Here's a look at how Spain got to this point and what may happen next. The independence declaration could happen as early as Wednesday or Thursday when the regional parliament meets. The European Union is standing solidly behind Spanish Prime Minister Mariano Rajoy and says Catalonia would be expelled from the bloc and the shared euro currency. Rajoy had insisted he couldn't discuss a referendum unless the constitution was changed, and invited Catalonia to work on changing it. Catalonia now wants the EU to intervene, an unlikely prospect, and calls for international mediation, something Spain is not likely to agree to.
