**Linke secured over 20% of the vote and the largest parliamentary bloc, and the Greens earned a mid-teens share.**

The Left (Linke) won the Berlin state election on Sunday, securing the largest share of seats in the state parliament. Its vote share exceeded 20 percent, placing it ahead of all other parties. The Christian Democratic Union (CDU) finished second, retaining more votes than the Alternative for Germany (AfD). The Greens fell to fourth place with a vote share measured in the mid-teens.

By surpassing the 20-percent threshold, Linke captured enough mandates to form the leading parliamentary faction. The result gave the party a decisive advantage in coalition talks.

The CDU's performance placed it ahead of the AfD, confirming its position as the main centre-right contender. Although it did not overtake Linke, the party retained a solid base that translated into a substantial bloc of seats. Its vote total remained well above that of the AfD, keeping the latter out of second place.

The AfD secured third place in the election, trailing both Linke and the CDU. Its vote share kept it behind the centre-right bloc but ahead of the Greens and other smaller parties. The party's standing ensured it remained a significant opposition force within the parliament.

The Greens received between 14 and 17 percent of the vote, placing them fourth overall. This level of support translated into a reduced number of seats compared with the leading three parties. The result limited the Greens' leverage in any prospective governing coalition.

## Analysis

With the largest bloc of seats, Linke is now the primary driver of any future governing coalition, influencing policy direction and agenda-setting.

The CDU's second-place finish confirms its role as the principal centre-right force, but the gap to Linke reduces its bargaining power. The party will need to decide whether to join a coalition led by Linke or remain in opposition, a choice that will affect its strategic positioning ahead of national elections.

AfD's third-place result sustains its presence as a notable opposition voice, though its inability to overtake the CDU limits its influence on coalition formation. The party's standing may still allow it to shape debates on security and immigration issues within the parliament.

The Greens' mid-teens vote share and fourth-place ranking diminish their leverage in coalition negotiations. Their reduced seat count means they are less likely to be a kingmaker, potentially forcing them to align with larger parties to impact environmental and social policies.
