Catalonia vote: 'A very important day' for Barcelona - mayor

The people of Catalonia in north-eastern Spain are voting in a disputed and non-binding poll on independence.

The Spanish judiciary has ruled the vote unconstitutional but Catalan leader Artur Mas warned against any attempt to disrupt it.

Prime Minister Mariano Rajoy said the vote would have no effect and urged the region to return to "sanity"

Speaking to the BBC outside a polling station, the Mayor of Barcelona said of his city: "We want to decide what we want to be".
