Batlle Berres was a journalist and prominent member of the Uruguayan Colorado Party. He was selected — in hindsight, with far-reaching effect — to serve as Vice Presidential running-mate for Luis Tomás Berreta.
He served as Vice President of Uruguay in 1947, succeeding Alberto Guani and held this office upon the death of President Berreta.
Batlle Berres was the fourth person to hold the office of Vice President of Uruguay. The office dates from 1934, when César Charlone became Uruguay's first Vice President.
He was President of Uruguay from 1947 to 1951, being succeeded in the office by Andrés Martínez Trueba.
Within the Colorado Party, he is now widely acknowledged for being the founder of the political branch known as Neo-Batllism. In this first period of Presidential office, the Vice President of Uruguay was Alfeo Brum.
Batlle Berres was President of the National Council of Government of Uruguay from 1955 to 1956. Batlle thus both preceded and succeeded Andrés Martínez Trueba as President.
The great great grandson of Catalan settlers from Sitges, Spain, he was the son of another political figure, Luis Batlle y Ordóñez, brother of ex president José Batlle. His mother, Petrona Berres, was of Irish descent and died when he was still a small child. Then, his father remarried but died soon after, in 1908. As a result, he went to live with his uncle, José Batlle y Ordóñez, the three-time President of Uruguay, and his cousins César, Rafael and Lorenzo Batlle Pacheco on the Piedras Blancas estate in the suburbs of Montevideo.
In 1927, he married Matilde Ibáñez Tálice, with whom he had three children: the also ex president Jorge Batlle, concert pianist Luis Batlle and Matilde Linda Batlle, the latter born in Argentina.
He was a member of the Colorado Party.
