The PM has called on the central committee to hold an internal ballot on the bail-out conditions in September, when any preliminary deal with creditors is likely to be done. Syriza's hard Left elements however are pushing for the vote to happen as soon as possible. A show of disunity would undermine the PM's position over the course of negotiations with creditors over the summer. It would also mean he would have to rely on opposition support to pass through any more "prior actions" legisation.
