EXPLAINER: How do other democratic nations select leaders?
SPAINIn Spain, the Congress of Deputies elects the prime minister. In 1996, this led to an awkward situation for the would-be prime minister. As votes were being counted, Jose Maria Aznar's conservative Popular Party thought it won enough seats to make him prime minister. Then, the party that wins the largest number of the 650 constituencies generally takes power, with the party leader becoming prime minister. That means the prime minister must officially be approved by the Queen’s representative in New Zealand, the governor-general.
