He remained Minister of Home Affairs in the Kotelawala cabinet until he was defeated at the 1956 general elections by Aloysius Weerakoon from the Sri Lanka Freedom Party.

Contesting the March 1960 general election, he was again defeated by Weerakoon, but won the subsequent July 1960 general election, with Weerakoon switching to the United National Party and contesting the seat of Kundasale.

He sat in the opposition until the 1965 general election when he allowed Weerakoon to contest his seat as the United National Party candidate.
