Metropolitan mayor
In the political system of Italy, the metropolitan mayor (Italian: sindaco metropolitano) is the single-member body body at the head of the government of a metropolitan city, a territorial entity that came into force in Italy on 1 January 2015. This position was not introduced by Legislative Decree No. 267/2000 ("Consolidated Law on the Organisation of Local Authorities"), which unlike Law No. 142/1990 did not list the bodies of the metropolitan city, and was instead established and regulated by Law No. 56 of 7 April 2014, containing "Provisions on Metropolitan Cities, Provinces, Unions, and Mergers of Municipalities".
