UPDATE: Spain’s Constitutional Court bans Sunday’s vote in Catalunya

SPAIN’S Constitutional Court has unanimously agreed to ban Sunday’s vote in Catalunya.

Catalan authorities planned to hold an informal poll after referendum plans were suspended by the court when the Spanish government presented a legal challenge.

Opinion surveys indicate most Catalans want a referendum but are equally divided over independence.

Tens of thousands of people are still expected to turn out on Sunday to hold demonstrations and attempt to vote anyway.

Civil organizations and even some town halls have pledged they will organize ‘unofficial’ ballots.

It is not clear whether the Spanish government will order arrests or other legal action against Catalans who organize unofficial ballots on Sunday.
