On 29 January 2016, Mexico City ceased to be the ''Federal District'' (Spanish: ''Distrito Federal'' or D.F.), and was officially renamed "Ciudad de México" (or "CDMX"). On that date, Mexico City began a transition to becoming the country's 32nd federal entity, giving it a level of autonomy comparable to that of a state. It will have its own constitution and its legislature, and its ''delegaciones'' will now be headed by mayors. Because of a clause in the Mexican Constitution, however, as it is the seat of the powers of the federation, it can never become a state, or the capital of the country has to be relocated elsewhere.
