Libya's General National Congress on Tuesday failed to agree on what action to take about the embattled government of Prime Minister Ali Zeidan, a member said.
His administration has been under fire for failing to tackle security problems and end an oil crisis that has dragged on for months after protesters shut key terminals, accusing the authorities of corruption.
"The political groups that met on Tuesday did not reach a consensus to bring the government down," Asma Sriba, a member of the GNC, the country's highest political authority, told AFP.
"Tomorrow (Wednesday) the coordinators of the political groupings will meet again to try to reach a common view on wide-reaching reforms concerning not only the government but also the congress," she said.

On December 29, dozens of protesters calling for Zeidan's resignation blockaded the premier's office and foreign, agriculture and telecommunications ministries in Tripoli for several hours.
Dozens of demonstrators also gathered outside the GNC building on Tuesday and tried to stop lawmakers from leaving until they had withdrawn confidence in the government.
But members of the security forces ensured GNC members were able to leave.
Dissatisfaction with the GNC has been mounting since it passed a resolution at the end of December extending its mandate until December 24, 2014.
The congress was elected in July 2012 to draft a new constitution and pave the way for general elections within 18 months following the ouster and death of dictator Moamer Kadhafi in October 2011.
Under the original timetable, the body's mandate had been due to expire in February.
