Berlin Left Party Victory Puts Housing Policy and Coalition Risks in Focus

The Left Party has won the election to Berlin’s House of Representatives, taking first place in Germany’s capital and dealing a setback to Chancellor Friedrich Merz’s conservative Christian Democratic Union. According to official preliminary results released overnight into Monday, September 21, the Left Party secured 25.7% of the vote, a gain of 13.5 percentage points compared with the 2023 election.

The CDU finished second with 18.8%, while the far-right Alternative for Germany placed third on 16.3%. The Greens won 14.3%, followed by the Social Democrats on 12.1%. The left-populist Sahra Wagenknecht Alliance, with 4.7%, and the liberal Free Democrats, with 2.5%, failed to clear the five percent threshold required to enter the Berlin parliament.

The result gives the Left Party 47 seats in the new House of Representatives. The CDU will hold 35 seats, AfD 29, the Greens 26 and the SPD 22. Voter turnout was 74.2%.

Coalition arithmetic matters beyond Berlin

For British and European business audiences, the Berlin result is not only a local political story. The German capital is a major administrative, property and technology centre, and the election outcome places housing policy, public spending priorities and coalition stability at the centre of the city’s next political cycle. London investors with exposure to German real estate, European equities or currency-sensitive assets will be watching the coalition talks closely, even though the preliminary results themselves did not include financial market data or any official assessment of sterling’s movement.

The immediate question is whether the Left Party can assemble a governing majority. Its potential partners are widely seen as the Greens and the SPD. Such a coalition would have enough parliamentary weight, but negotiations are expected to be difficult because the parties disagree on several major issues.

Elif Eralp, the Left Party’s leader in Berlin, said she expected to become governing mayor of the German capital.

“The residents of Berlin have given us a clear mandate to lead the city,” Eralp said.

That claim will now be tested in talks with parties that share parts of the Left’s social agenda but differ over policy detail and political risk. The CDU’s second-place finish means Merz’s party remains a major force in the city, but the result deprives the conservatives of first place in one of Germany’s most visible political arenas.

Property policy will draw close attention

The most consequential issue for business may be housing. The Left Party and the Greens want to implement the decision taken in a 2021 city referendum to expropriate more than 200,000 apartments from large housing companies. The SPD opposes that plan.

For investors in London and across Europe, that dispute is likely to be the central policy signal from the election. Berlin’s residential property market is already closely watched because of its size, political sensitivity and role in wider debates over affordability in European cities. A renewed push for expropriation would raise questions for landlords, asset managers, pension funds and lenders with direct or indirect exposure to German housing companies. The source results do not provide company-level data, asset valuations or market pricing, but the political direction is clear: any governing coalition led by the Left Party would face pressure to act on the referendum mandate.

The housing debate also has a broader European dimension. Large cities across the continent face pressure over rents, supply constraints and the role of institutional landlords. Berlin’s next government could therefore influence policy arguments beyond Germany, including in markets followed by British investors seeking comparisons with London, Manchester and other urban centres.

For sterling, the election is a political development rather than a direct currency event based on the figures reported. The source material contains no exchange-rate data and no evidence of an immediate London market reaction. Still, UK market participants often track German state and city-level results as indicators of political fragmentation, policy direction and investor sentiment inside the eurozone’s largest economy.

Antisemitism and controversy complicate talks

Coalition negotiations could also be shaped by concerns over antisemitism. Eralp has repeatedly stressed that she wants to support and develop Jewish life in Berlin. However, the Left Party faces criticism from potential coalition partners on the issue.

Felix Banaszak, co-chair of the Greens, has said a coalition with the Left Party is possible, but only if the party demonstrates a clear position against antisemitism. That condition introduces another political test for Eralp as she seeks to convert an election win into executive power.

The election night also produced a controversy involving Issa Remmo, identified by German media as the head of the well-known Remmo clan of Arab origin. He was seen at a Left Party gathering in Berlin’s Neukölln district after voting ended.

The Left Party has distanced itself from Remmo. Party representatives said the event was open and that anyone could attend. Speaking on ZDF, Eralp said: “We have nothing to do with organised crime.”

Other parties have criticised the Left over the episode. Nina Stahr, head of the Greens in Neukölln, demanded explanations from the party’s potential coalition partners and linked the matter to talks on forming Berlin’s new government.

The final shape of the administration will determine how far the election result translates into policy. A Left-Green-SPD coalition would have to reconcile competing positions on housing, public trust, antisemitism and the political management of Germany’s capital. For British and European businesses, the key question is whether Berlin’s next government pursues an assertive interventionist programme or moderates its agenda in the search for a stable coalition.
