When Alexis Tspiras resigned his premiership earlier this month and called for a snap election, it signaled a new round in the ongoing battle between Greece and its creditors.

For Tsipras, next month’s election represents an attempt to secure a mandate for the deal Syriza has signed off on. Yet the former prime minister’s approval rating has dropped from 61 percent to 29 percent in the last month. Almost 80 percent of voters say they’re disappointed with Tsipras’s performance during Syriza’s time in office. And 70 percent think the bailout package the leadership approved will deliver more economic pain than the previous two austerity agreements.

It is to this discontent which Popular Unity, a new formation of dissident Syriza members and other anti-austerity forces, hopes to give institutional expression.
