Germany’s Hamburg election: Greens expected to make big gains

Sunday’s vote is about deciding who gets elected into this parliament.

The German city-state of Hamburg heads to the polls on Sunday in an election which is being seen as a test for the country’s established parties.

For the last 10 years, Hamburg has been a political stronghold of the Social Democrats.

But its coalition partner, the Green party, is eyeing first place.
