Will he still come out of it looking good or are people starting to doubt him?
I haven't been following that closely
I guess that depends on the result of the referendum. If the Greeks vote overwhelmingly against the bailout terms, then they are sticking with Syriza. If they vote for them, then they are going with the EU plan and, therefore, moving back towards the thinking of the more mainstream parties. At that point, I'd have thought Syriza would become fractured as a party and that the far-right might become more popular as the party of the anti-EU/austerity movement.
My understanding of this whole situation is fairly limited, so take what I post with a pinch of salt!
