According to the Berlin Constitution, the Governing Mayor is member and head of the Berlin Senate. The ministers are called senators. The two deputies additionally hold the title of Mayor (German: Bürgermeister, historically: burgomaster). The title Mayor is also held by the heads of the twelve boroughs of Berlin, although they do not actually preside over self-governmental municipalities.
The Governing Mayor is elected by the city´s state parliament, the Abgeordnetenhaus of Berlin (equivalent to the Landtag of other federal states), which also controls their policy guidelines and is able to enforce resignation by a motion of no confidence. The Governing Mayor is entitled to appoint and release the senators of the government.
