Brazilian Marshal Humberto de Alencar Castelo Branco is elected president by the National Congress.

Humberto de Alencar Castelo Branco was a Brazilian military officer and politician who served as the 26th president of Brazil, the first leader of the Brazilian military dictatorship following the 1964 coup d'état. He was a member of a more liberal "legalist" faction within the regime, as opposed to his more authoritarian successors.

The National Congress is the legislative body of Brazil's federal government. Unlike the state legislative assemblies and municipal chambers, the Congress is bicameral, composed of the Federal Senate and the Chamber of Deputies. The Congress meets annually in Brasília from 2 February to 22 December, with a mid-term break taking place between 17 July and 1 August.
