The election of Ahmed Maiteeq as new prime minister is invalid, Libya's parliament vice-speaker declared in a letter published on a government website. Maiteeq had failed to obtain the necessary quorum during a parliamentary vote earlier on Sunday, First Parliament Vice-Speaker Ezzedin al-Awami said in the letter, Reuters reported. Libya continues to experience political uncertainty after former PM Abdullah al-Thinni resigned three weeks ago. His government will stay in office until a successor is elected legally, al-Awami wrote.
