While the elections for a 200-member National Congress is unlikely to grant a majority to any one faction, the Muslim Brotherhood and its Islamist allies are confident they can join their counterparts in Tunisia and Egypt at the helm of leadership.

Negotiations between the Muslim Brotherhood and a secular-based political movement led by former interim prime minister Mahmoud Jibril have focused on forming a post-election government as soon as the result is known.

An adviser to Mr Jibril said the former prime minister was likely to take the post of figurehead president with Mustafa Abu Shagour, currently interim deputy prime minister of the Muslim Brotherhood, taking the prime minister’s slot as head of government.

The Muslim Brotherhood would dominate the ministries.

In the run-up to the elections, Libya’s interim government has struggled to maintain law and order.
