for the creation of autonomous communities, but the process itself was embryonic in nature – they were formed after the promulgation of the constitution, and the outcome was unpredictable – the constituent assembly chose the province as the basis for territorial representation. The Senate has less power than the Congress of Deputies: it can veto legislation, but its veto can be overturned by an absolute majority of the Congress of Deputies. Its only exclusive power concerns the autonomous communities, thus in a way performing a function in line with its nature of "territorial representation".

The candidate then presents the political program of his or her government requesting the Congress's confidence. If the Congress grants him confidence by absolute majority, the King then nominates him formally as "president of the Government"; if he or she fails to obtain absolute majority, the Congress waits 48 hours to vote again, in which
