Libya's new prime minister, Ali Zeidan, has two weeks to name his cabinet and submit it for approval by the national assembly.

Zeidan, a former diplomat and lawyer, secured only a narrow victory in yesterday's run-off in the General National Congress (GNC). He defeated local government minister Mohamed al-Harari by 93 votes to 85, suggesting that he does not enjoy overwhelming support within the assembly and that forming a cabinet that appeases all political and regional factions may, again, not be straightforward.

The new premier's predecessor, Mustafa Abu Shagour, was elected on 12 September but was then dismissed less than a month later after failing to secure support for two proposed cabinets - the first containing around 28 ministers, the second an "emergency" line-up with just 10 names.

A key point to watch in Zeidan's proposed government will be whether various economic and infrastructure posts are combined or separated. Abu Shagour's first cabinet included separate posts for electricity, water, public works, housing and utilities, finance, economy, communications, transport and industry.

His second proposal combined housing and public works into a single portfolio and amalgamated the economy and finance ministers into one post.

Zeidan says his new cabinet will be an "emergency" government with a priority on improving security in Libya.
