Greece turns left as Europe goes right

Why has Greece chosen a far-left government at a time when discontented and frustrated voters elsewhere in Europe have turned to the far right?

In northern Europe, the frustrated voters’ parties of choice are right wing and anti-immigrant. So how come frustrated Greeks made a sharp turn to the left, electing the near-communist Syriza party to lead the government?

The choice of left over right is especially striking because Greece is a first port of call for so many new immigrants to Europe.
