More than four years into debt-stricken Greece's prolonged economic crisis, many described the step as the height of humiliation for a nation already hit by excoriating austerity and record levels of poverty and unemployment."The government is constantly trying to convey the message that the economy is a success story but in reality that is not the case at all," said prominent leftwing campaigner Petros Constantinou. "The decision to put public buildings up for sale is not just proof that they are nowhere near reaching targets but plain wrong when they could be exploited for public benefit."Under immense pressure to enact reforms for the release of a long overdue €10.1bn (£8.5bn) aid instalment from international creditors, prime minister Antonis Samaras' fragile two-party coalition handed the real estate to the fund overseeing the sale of state assets (Taiped) last week.
