A blueprint for a post-Qaddafi Libya would retain much of the current regime's infrastructure in the hope of averting an Iraq-style descent into chaos, the London Times reports.

The 70-page plan prepared by the National Transitional Council (NTC) with help from Western powers concedes Libya's rebels have little chance of toppling Qaddafi, but maintains internal divisions will force him out.

In that event, the rebels plan to establish a 10,000-15,000 strong "Tripoli task force" to secure the capital and capture key Qaddafi supporters. Around 5,000 policemen will be recruited to serve as the interim government's security forces, according to the plan.

The rebels claim some 800 current Qaddafi government officials have already been recruited to their cause, and could form a key plank of a post-conflict security apparatus.

The document also maps out how telecommunications, power and transport infrastructure will be secured in the immediate hours after the regime's collapse.

The rebels estimate that around 70 per cent of high-ranking Qaddafi officials will commit to the new regime.

The NTC confirmed the report's authenticity, but requested that the newspaper withhold key details which could compromise the ongoing operation.

Aref Ali Nayed, the head of the planning cell for the task force, said it was important that the general public "knows that there is an advance plan".

"What you have obtained was an early draft," he told the paper. "We are now working on a much bigger picture."

But analysts say the plan is little more than wishful thinking if no clear end to Qaddafi's nearly 40-year rule is on the horizon. 

The report was revealed as rebel fighters find themselves running low on ammunition as they struggle to maintain their gains in the face of a renewed offensive by Qaddafi.
