BERLIN: To many German Social Democrats it sounds like a monster that will destroy their party if not democracy itself: the GroKo.

The term is shorthand for “grand coalition”, the mega-alliance of Chancellor Angela Merkel’s conservatives and their own SPD labour party that has ruled Europe’s top economy for the past four years, reports AFP.

“Never. Again. GroKo,” read a pin-on button handed out by the party’s youth wing at a fractious party congress in Berlin last week that was dominated by painful soul-searching over its worst election result in post-war history.

The blunt message was illustrated with a picture of two hands forming a diamond shape, Merkel’s standard gesture in front of cameras, which has come to symbolise the veteran chancellor dubbed “Mutti” (mummy).

“We don’t want a grand coalition,” said one member, Michelle Rauschholb, 25, who fears the SDP will be forced to “betray its ideals” if it has another stint as Merkel’s junior partner.

Going into talks with Merkel this Wednesday, SPD chief Martin Schulz is deeply sceptical about another GroKo power pact, and aware much of his party base is openly hostile to another coalition.

But after months of post-election deadlock, Schulz has agreed to meet Merkel to sound out plans to give the unhappy partnership another lease of life, even though many Social Democrats fear it spells a mortal threat to their 150-year-old party.

The U-turn came after Schulz declared on the night of his September 24 election defeat that he would take the battered party into opposition rather than again play second fiddle to Merkel.

But he had to eat his words three weeks ago when Merkel’s efforts to build an alternative alliance with two smaller parties collapsed and pressure rose on the SPD to avert political paralysis.

Schulz consented to “open-ended” talks that may or may not allow Merkel to lead another GroKo government from sometime in early 2018.

At the Berlin party congress, speaker after speaker argued passionately that to again govern under Merkel would further weaken the party’s message and credibility.

The revolt was led by the party’s youth wing, which collected reasons against a GroKo in messages stuck onto a white board.

“Political suicide,” read one, while another stated: “GroKo is the final nail in the coffin of Social Democracy.”
