In September 1968 the DLF was renamed the Popular Front for the Liberation of the Occupied Arabian Gulf (al-Jabha al-Sha'abiya li-Tahrir al-Khalij al-'Arabi al-Muhtall, PFLOAG).

Its members were inclined towards the leftist, Marxist-Leninist tendency in the ANM, and were also influenced by the revolutionary experience of neighbouring South Yemen.

The new organisation was called Popular Front for the Liberation of Oman and the Arabian Gulf (al-Jabhah al-Sha'abiyah li-Tahrir 'Uman wa-al-Khalij al-'Arabi, PFLOAG).

It suffered a split in 1970 when some of its more right-wing members decided to accept the offer of an amnesty from the newly enthroned Sultan Qaboos.

In 1992, the party was renamed to People's Democratic Front of Oman (al-Jabhah al-Sha'abiyah al-Dimuqratiyah al-'Umaniyah, PDFO) which struggles peacefully for democracy.
