Berlin Left Party win points to sharper economic fights over housing

The Left Party has emerged as the strongest force in elections to Berlin’s House of Representatives, according to official preliminary results, reshaping the political balance in Germany’s capital and putting the city’s unresolved housing crisis at the center of coalition talks.

The vote, held on September 20, gave the Left 25.7 percent, an increase of 13.5 percentage points compared with the 2023 election. The Christian Democratic Union, the party of German Chancellor Friedrich Merz, finished second with 18.8 percent. The far-right Alternative for Germany placed third with 16.3 percent, followed by the Greens on 14.3 percent and the Social Democrats on 12.1 percent.

Two parties fell short of the five-percent threshold for entry into the Berlin parliament: the left-populist Sahra Wagenknecht Alliance, with 4.7 percent, and the liberal Free Democrats, with 2.5 percent. Turnout was 74.2 percent.

The preliminary seat distribution gives the Left 47 seats in the new House of Representatives, the CDU 35, the AfD 29, the Greens 26 and the SPD 22. That arithmetic makes a government led by the Left plausible, but not automatic. Potential coalition partners are expected to be the Greens and the SPD, yet negotiations are likely to be difficult because the parties diverge on several politically and economically consequential issues.

“Berliners have given us a clear mandate to lead the city,” Left Party leader in Berlin Elif Eralp said.

Housing policy moves to the center

Eralp said she expects to become the governing mayor of the German capital. If she succeeds, Berlin would enter a new political phase in which the city’s housing market, already one of the most contentious in Europe, becomes the main test of whether a left-led coalition can convert electoral momentum into policy.

The clearest dividing line concerns a 2021 city referendum calling for the expropriation of more than 200,000 apartments from large housing companies. The Left and the Greens want to implement that decision. The Social Democrats oppose the plan. That disagreement is not a narrow technical dispute; it goes to the structure of urban economic policy in a city where rent pressure, private ownership concentration and public-sector capacity have become defining questions.

For Berlin, the referendum issue carries historical weight. The city has long been shaped by experiments in housing policy, from municipal and cooperative traditions to more recent privatization and efforts to regulate rent growth. A move to expropriate large landlords would mark a far-reaching intervention in property rights and housing supply, with consequences beyond the capital. It would be watched by investors, tenants’ groups, other German cities and federal policymakers as a test of how far local governments can go in responding to affordability pressures.

Supporters of the plan see it as a structural answer to a structural problem: a housing market in which rising rents have outpaced many residents’ incomes and where market supply has not eased political pressure. Opponents warn that expropriation could deter investment, create fiscal risks and fail to add enough new housing stock. The SPD’s resistance therefore matters not only as a coalition obstacle, but as a signal that the future government’s economic program may be constrained by concerns over budget exposure, legal complexity and administrative capacity.

The Left’s strong showing also highlights a broader shift in voter priorities. A gain of 13.5 percentage points from the 2023 election suggests that the party successfully captured discontent over urban living costs and social policy. In economic terms, the result points to a demand for redistribution through local government: more intervention in housing, stronger tenant protections and a larger role for public authorities in shaping essential markets.

Coalition risks and reputational tests

Coalition talks will not revolve around economics alone. Another sensitive issue is antisemitism. Eralp has repeatedly stressed that she wants to support and develop Jewish life in Berlin, but the Left faces criticism from potential coalition partners. Greens co-chair Felix Banaszak has already described a coalition with the Left as possible only if the party demonstrates a “clear position against antisemitism.”

That condition introduces an additional layer of risk for the Left. In a city with Berlin’s history and international profile, questions of antisemitism are not peripheral to governing legitimacy. They can influence coalition discipline, public trust and the willingness of partners to share political responsibility. For an incoming administration seeking to pursue contentious housing reforms, reputational confidence may become an economic asset in itself: without it, ambitious policy could be harder to negotiate, defend and implement.

The party also faced criticism after Issa Remmo, whom German media describe as the head of the well-known Remmo clan of Arab origin, was seen at a Left Party gathering in Berlin’s Neukölln district on the evening after voting ended. The Left distanced itself from Remmo, saying the party was open and anyone could attend. Eralp told ZDF: “We have nothing to do with organized crime.”

Other parties nevertheless criticized the Left. Nina Stahr, head of the Greens in Neukölln, demanded explanations from the potential coalition partner and linked the matter to negotiations over the formation of Berlin’s new government.

The episode may complicate talks at a moment when the Left needs to reassure both potential partners and the wider electorate that it can govern a complex metropolis. Berlin is not only a symbolic capital; it is a large service economy, a housing market under pressure and a fiscal unit whose policies can influence national debates. A left-led coalition would have to prove that it can manage public finances, security controversies and social demands while pursuing a more interventionist economic agenda.

The election therefore leaves Berlin with two parallel stories. One is political: the Left has won first place and can plausibly claim a mandate to lead. The other is economic: the hardest questions now move from campaign platforms to coalition contracts, especially the future of large housing portfolios, the balance between tenant relief and investment incentives, and the fiscal consequences of implementing a referendum that has remained unresolved since 2021.
