Greek debt crisis: Alexis Tsipras hopes to win bailout vote as protests turn violent

Embattled prime minister fights to outflank opposition to eurozone agreement as riot police use teargas on demonstrators outside Athens parliament

Alexis Tsipras is fighting for his political life as he seeks parliamentary backing for the severe austerity measures Greece has pledged to take in exchange for a fresh bailout from its eurozone partners.

The Greek prime minister urged his Syriza colleagues to support him in the make-or-break vote on Wednesday night, even as the International Monetary Fund - and his own former finance minister and right-hand man Yanis Varoufakis - savaged the deal struck in the early hours of Monday morning.
