In a rare televised statement, King Felipe said the referendum's organizers had jeopardized national stability. "With their decisions, they have systematically undermined the rules approved legally and legitimately, showing an unacceptable disloyalty towards the powers of the state -- a state that represents Catalan interests," he said, CNN reports.
King Felipe's hardline address was an unusual departure for the Spanish monarch, who used the majority of his speech to castigate Catalan leaders while making no reference to polling day violence that left nearly 900 people injured. He concluded the address with a call for national unity, while continuing to unleash a verbal assault on the Catalan authorities.
