Can you tell us more? Why he was dismissed, on which issue, by a coalition of representatives of what tendency. Because, AFAIK, there's nothing inherently islamist about dismissing a PM.

Sorry. I fixed the link.

I think he had trouble forming a cabinet, especially with many want the new cabinet to reflect Libya's tribalism.
Abu Shagur was fairly liberal, by Middle Eastern standards. I just fear that this could open up a new "can of worms" should the next PM also fail to assemble a cabinet.
