Looks like Alexis Tsipras' Syriza MPs defected in a big way: 32 No votes this time with 11 abstentions and 1 absent. This could prove fatal to Tsipras' continuance as Prime Minister. The Syriza coalition of the Left with 149 members partners with Independents with 12 in the 300 seat parliament. Tsipras' core support in parliament appears to have fallen to 39%.
The "erratic Marxist" Yanis Varoufakis voted No, after voting Yes and No previously, and reportedly offered to resign his seat so that Tsipras may appoint a reliable vote to replace him.
