Takasia is correct.
Under the Spanish constitution, the King can dissolve Parliament at will, and run the country without the President, though the monarchy has not done so since the early years after the fall of Franco. Also, multiple languages are spoken, including Castillian, Aragonese, Catalan, Euskadi, Andalusian, and Portugese. Castillian is what is known as "Spanish", and is only as widespoken as it is because of Franco's dictatorship.
