In 1959, Mohamed Nasir started his active politics with PAS and was appointed as Deputy Chief Minister of Kelantan.

After the lifting of the Emergency in February 1978 and subsequently the snap elections of Kelantan in March 1978, which BN won with support of Berjasa, Nasir were replaced by Mohamed Yaacob from BN-UMNO as Menteri Besar.

He later were appointed as Minister without Portfolio in the leadership of the Barisan Nasional government from 1978 to 1982, when Berjasa were admitted to BN after the 1978 Malaysian general election.
