President pro tempore

A President pro tempore is a constitutionally recognized officer of a legislative body who presides over the chamber in the absence of the normal presiding officer. The phrase “pro tempore” is Latin “for the time being”.

In Argentina, a similar role is carried by the Provisional President of the Argentine Senate in the absence of the Vice-President of Argentina who is designated, by the 1994 amendment to the 1853 Constitution, as the Senate President.
