Next Greek Election Date

Will Greece hold a legislative election before the end of 2015?
Yes: 65%
(A referendum or by-election would not count for purposes of this question)

The Greek PM, Alexis Tsipras, has called for a confidence vote next week (see story here).  If he loses the vote, elections will be held in September.  Many MPs in his own party voted against the recent bailout deal, which was supported by Tsipras.  The main opposition party, New Democracy, will not be supporting Tsipras in the confidence vote.

From what I can tell, Tsipiras will probably lose the upcoming confidence vote.  Even if he does win this vote, an election could be held later in the year due to another confidence vote.  Greece has held closely spaced elections before; it held two legislative elections in 2012 after the first election failed to lead to a stable government.
