The Liberal Party won control of the chamber after having ten seats out of the 24-member Senate, as the 2-member Grand Alliance (the old Progressive Party) were caucusing with them, plus Alejandro Almendras of the Nacionalistas who personally supported Senate President Ferdinand Marcos.

The Nacionalista Party and the Liberal Party each won four seats.

Nacionalistas Arturo Tolentino and Gil Puyat, and Liberal Ambrosio Padilla all defended their seats.

Five winners are neophyte senators. These are Juan Liwag, Gerardo Roxas and Tecla San Andres Ziga of the Liberal Party, and the Nacionalistas' José W. Diokno and Rodolfo Ganzon.

Incumbent Nacionalista senators Eulogio Balao, Roseller T. Lim and Cipriano Primcias Sr., and Rogelio de la Rosa of the Liberal Party all lost.
