Coalitions & government

Coalition reality

Who can realistically govern together?

Germany's arithmetic is only half the story. Parties also have formal red lines, historical partnerships and major policy conflicts. This matrix describes political compatibility—not constitutional eligibility and not a prediction.

Hardest red lines: CDU's standing resolution rejects coalitions and similar cooperation with both AfD and Die Linke; the SPD says there will be no cooperation with the AfD; the Greens likewise explicitly reject cooperation with the AfD.[47][48][49] The rest of the matrix is an analytical synthesis of programme distance, current parliamentary status and recent Land-level precedents—not an official party document.
Power today

Who actually governs?

Manifestos show preferences; governing requires coalition compromise. The current federal coalition agreement therefore matters at least as much as the 2025 election programmes.

Federal executive

CDU / CSU / SPD

Friedrich Merz (CDU) is Chancellor. The government consists of the Chancellor and 17 federal ministers.[3]

Coalition priorities are described by the government as economic strength, stable finances, security, social cohesion and responsible foreign policy.[4]

Federal opposition

AfD · Greens · Die Linke

These are the three opposition parliamentary groups. Current group sizes: AfD 150, Greens 85, Linke 64.[2]

The AfD is the largest opposition group; Greens and Linke often oppose the government from very different policy directions.

No Bundestag group

FDP · BSW

Both failed the 5% threshold in 2025. BSW missed it exceptionally narrowly at 4.981%; FDP received 4.3%.[1]

They can still hold European, Land and municipal mandates and influence coalition politics outside the Bundestag.

2021–2024/25 · “Traffic-light” era

SPD, Greens and FDP governed federally under Olaf Scholz until the coalition collapsed in late 2024, triggering the early 2025 election.

23 Feb 2025 · Federal election

Union first (28.5% combined), AfD second (20.8%), SPD third (16.4%); FDP and BSW outside parliament.[1]

6 May 2025 · Merz government

CDU/CSU and SPD formed the new federal government after signing the “Verantwortung für Deutschland” coalition agreement.[44]

2026 · Opposition reshapes

AfD rose to first place in the September ARD poll; Greens and Linke also poll above their 2025 election results, while the governing Union and SPD poll below theirs.[5]

6 Sep 2026 · Saxony-Anhalt

Election night produced a historic AfD breakthrough. Final/provisional official data were not yet published when this snapshot was locked, so coalition consequences remain open.[42][43]

A subtle but important point: the current Bundestag has 3 unaffiliated members. Two are former AfD members, while Stefan Seidler represents the SSW, the Danish/Frisian minority party. Minority parties such as SSW are exempt from the normal 5% threshold, which is why a 0.2% national vote can still yield a seat.[2]
