Catalonia independence: Spanish region set for informal poll

Sunday's informal vote on Catalan independence will have "no effect", Spain's prime minister has said.

The referendum, called by the nationalist regional government of Catalonia, was ruled unconstitutional by the country's highest court, following an appeal by Mariano Rajoy.

Many Catalans believe the Spanish state gives their region a raw deal financially and that it refuses to accept their cultural differences and language.
