The Politics of Trentino-Alto Adige/Südtirol, Italy takes place in a framework of a parliamentary representative democracy, whereby the President of Regional Government is the head of government, and of a pluriform multi-party system. Executive power is exercised by the Regional Government and Legislative power is vested in both the government and the Regional Council. However, since a constitutional reform in 1972, almost all the executive and legislative powers are devolved to the two provinces of which the region is composed: Trentino and the South Tyrol.
