Investiture and formation

Italy's prime minister is appointed by the president after post-election consultations and must win confidence in both chambers of parliament. Spain's prime minister must win an investiture vote in the Congress of Deputies, with a mechanism for simple-majority fallback that can help minority governments form.

Government stability

Italy has had far more frequent government changes, with over 70 governments since 1946, partly because any simple-majority no-confidence vote can topple the government. Spain adopted a constructive no-confidence mechanism requiring opponents to propose an alternative prime minister, which has contributed to longer government tenures.

Party system fragmentation

Italy's party system is highly fragmented and has undergone multiple complete restructurings, with entirely new parties rising to dominance within a single election cycle. Spain's party system was long dominated by two major parties (PSOE and PP) before newer forces like Podemos, Ciudadanos, Vox, and Sumar created a more complex multiparty landscape.

Regional and territorial politics

Both countries face strong regional pressures — Italy through North-South economic divides and autonomist movements, Spain through Catalan and Basque nationalism that can make or break governing coalitions. In both systems, the prime minister must manage territorial tensions alongside parliamentary arithmetic.
