Tripoli , Libya ( CNN ) -- Confusion and uncertainty swirled in Libya over the results of a vote on Sunday by the interim parliament on a new interim prime minister as disagreements over the legality of the outcome have been raised . Initial reports indicated the country 's General National Congress elected businessman Ahmad Mitig as interim prime minister Sunday . Mitig was sworn in after reportedly receiving 121 votes in a volatile debate in the GNC that included multiple votes . After Mitig was sworn in , the GNC gave him two weeks to form a government . `` We hope it is less than two weeks . As you know , we rushed because the country can not bear this . We need a government to grant a budget in the coming days . ... We wish him luck , '' said a deputy parliament speaker who was chairing Sunday 's session . Then later Sunday , the First Deputy Speaker of Libya 's interim parliament , Ezzedin al-Awami , announced that the vote naming Mitig as interim PM was invalid . The parliament first failed to elect the new Prime Minister after a confidence vote fell short of the 120 votes needed . It took two rounds of voting before Mitig emerged as the frontrunner for the post , but in another confidence vote , he received only 113 votes . Speaker al-Awami said in a letter posted to the Libyan interim government 's Twitter account that the session was actually adjourned at this point , after Mitig failed the confidence vote and did not get the required 120 votes . `` ... continuing the process , increasing the votes and announcing that the candidate won the vote of confidence to form a Cabinet , is an invalid procedure and illegal , '' he said in the letter . Al-Awami is the acting speaker and highest-ranking elected official in Libya . The government also posted a second letter by al-Awami . This one was addressed to the caretaker prime minister , Abdullah al-Thinni . Al-Thinni , the country 's former defense minister , was chosen by parliament to temporarily take over for acting Prime Minister Ali Zeidan , who was voted out by parliament in March . Last month , al-Thinni was selected as the new Prime Minister , but he later stepped down after he and his family were attacked . He then agreed to continue as a caretaker until a new prime minister is chosen . In the letter , al-Awami asked al-Thinni to continue as caretaker Prime Minister until a new vote is held . Meanwhile , other parliament members insisted the vote on Mitig was legal and that he was rightfully elected interim Prime Minister . Until parliament reconvenes on Monday , it is not yet clear who the Libyan Prime Minister is . Political and security challenges are adding to the turmoil in the fledgling democracy . Libya 's government has been unable to impose its authority over a myriad of militia groups that have grown in power and influence since the 2011 revolution that toppled longtime dictator Moammar Gadhafi .
