Catalan regional president Artur Mas (2nd R) leaves the Generalitat palace after signing a decree calling early parliamentary elections in Barcelona, on August 3, 2015. The decree sets September 27, 2015 as the date for an early regional election that will serve as a proxy vote on independence from the rest of Spain, raising tensions with the central government in Madrid.
