bloody crackdown against a student uprising.
The boyish father of two children who admires Che Guevara -- naming his second son Orpheus Ernesto -- has subtly modified his image as power and responsibility beckoned.
He has made efforts to improve his English and sought to boost his international standing through meetings with Pope Francis, European Central Bank chief Mario Draghi and even Wolfgang Schaeuble, finance minister of Greece’s fiscal nemesis Germany.
One thing has not changed -- Tsipras’ shirts are likely to remain open-necked. On the eve of voting, he joked: “I’ll put a tie on when we get a haircut (debt reduction).”
Tsipras faced his first crisis in 2008 when Athens and other cities were rocked by youth riots following the fatal shooting of a teenage boy by a policeman.
Syriza gave the rioters political backing but the move backfired and in the next election the party took less than five percent of the vote.
But when the economic crisis engulfed Greece in 2010, plunging the country into the worst recession in memory, voters were more inclined to listen to Syriza.
He has accused the conservative-led coalition government of “denying reality” by “dogmatically” adhering to a failed austerity recipe that has left over one million people unemployed in a country of 11 million.
In three years, Syriza’s support has increased five-fold.
The outgoing conservatives of Prime Minister Antonis Samaras have argued that a Syriza government would overturn years of painful fiscal efforts just as Greece is about to reap the benefits.
But Tsipras turned the argument on its head, wondering how the conservatives could possibly promise to safeguard Greek incomes after imposing a barrage of taxes in the last two years.
“The only thing they have not said is that Syriza will round up children and steal wives,” he joked at one rally.
Syriza pledges to raise salaries and pensions, halt layoffs and freeze the privatisation of state assets, reversing key reforms demanded by Greece’s EU-IMF creditors.
Even more crucially for its relations with Greece’s EU peers, the party wants to renegotiate the 240-billion-euro EU-IMF bailout, erase over 50 percent of the country’s enormous debt and divert bond repayment funds to the country’s economic recovery.
