BERLIN — Chancellor Angela Merkel’s conservatives and the Social Democrats sealed a deal on Wednesday on a new coalition, officials close to the talks said, potentially ending four months of political standstill in Europe’s top economy.

The sources said the parties had ironed out their final differences and were ready to sign an agreement for Merkel’s fourth term.

Public broadcaster ARD said the final disputes had centered around “ministry remits and personnel questions”.

The breakthrough will come as a relief to Germany’s EU partners as the bloc faces tough negotiations on migration and Brexit.

Merkel, Europe’s most experienced leader, has seen her standing at home and abroad weakened by the longest stretch of coalition-building in the country’s postwar history.

But before she can be sworn in, a final hurdle looms: the hard-fought pact between her CDU/CSU bloc and the Social Democratic Party must still be approved by the SPD’s skeptical rank-and-file.

The agreement for a renewed “grand coalition” comes after days of marathon talks in which negotiators from all three parties haggled over everything from foreign policy to labor issues and healthcare.

Germany has been stuck in political limbo since September’s inconclusive general election saw mainstream parties bleed support to the far-right AfD, which tapped into anger over Merkel’s liberal refugee policy.

Merkel, in power for over 12 years, at first tried to cobble together a novel three-way coalition with the Greens and the liberal Free Democrats, but those efforts collapsed in November.

Faced with snap elections that could further boost the AfD or the prospect of heading an unstable minority government, she opted to woo back the SPD — her junior partner for two of her three terms since 2005.

SPD leader Martin Schulz then abandoned his post-election vow to renew the party in opposition — a U-turn that angered many.

Merkel’s fate now lies in the hands of the SPD, as Schulz has promised to give his party’s 460,000 members the final say on whether to accept the coalition pact.

Observers expect the referendum to be tight, with the SPD’s left and youth wings fiercely opposed to another four years governing in Merkel’s shadow.

The party’s fiery youth chief Kevin Kuehnert has led a campaign against another “GroKo”, as the grand coalition is known.

The referendum will be held by postal ballot, with the result expected to be announced in early March.

A green light could see a new Merkel-led government in place by the end of next month.

A thumbs-down could spell disaster for Merkel and Schulz, whose political lives hang in the balance, and see the country headed for fresh elections.

With so much at stake, Schulz was determined to extract as many concessions as possible from the tortuous coalition talks to win over skeptics.

While details of the final agreement have yet to be released, former European Parliament chief Schulz has put a fairer Europe at the heart of his efforts, insisting that Berlin must join French President Emmanuel Macron’s push to deepen eurozone integration.

In a draft version of the coalition pact seen by AFP, the parties agreed to support Macron’s reform drive and tentatively backed his idea of a eurozone investment budget.

On the hot-button topic of migration, the two camps said they would aim to limit the annual intake to 180,000-220,000 people, a key CSU demand.

The SPD however won assurances that family reunifications for refugees would resume in August, albeit restricted to 1,000 people a month. — AFP
