Greece's shaky coalition government scraped through a vote on Wednesday, July 17 on a bill to sack public sector workers as thousands chanting anti-austerity slogans protested outside parliament, Reuters said.

The vote was the first major test for Prime Minister Antonis Samaras's two-party coalition since losing an ally over the abrupt shutdown of the state broadcaster last month, which left it with a scant five-seat majority in the 300-seat parliament.

After midnight on Wednesday, 153 lawmakers out of the 293 present voted in favor of the bill, whose passage was required to unlock nearly 7 billion euros ($9.2 billion) in aid from European Union and International Monetary Fund lenders.

The bill includes deeply divisive plans for a transfer and layoff scheme for 25,000 public workers - mainly teachers and municipal police - that had triggered a week of almost daily marches, rallies and strikes in protest.

About 5,000 Greeks flooded the street outside parliament as the vote neared, with some chanting: "We will not succumb, the only option is to resist" and holding aloft black balloons - though turnout was much smaller than in protests last year.

The reforms were passed hours before German Finance Minister Wolfgang Schaeuble - Europe's leading proponent of austerity blamed by many Greeks for their woes - arrives in Athens for his first visit to Greece since the debt crisis began in 2009.
