In politics, a red–red coalition is a coalition government composed of social-democratic parties allying themselves with more radical democratic socialist or socialist parties, a coalition that spans the centre-left to the left or far left.
A specific example of a red-red coalition comes from the politics of Germany, formed from the Social Democratic Party of Germany (SPD) and The Left party or its predecessor, the Party of Democratic Socialism (PDS).[1] Red–red coalitions form state-level governments in Brandenburg, and historically have governed Berlin (2001–2011),[2] Mecklenburg-Vorpommern (1998–2006)[3] and (as a SPD minority government tolerated by the PDS) Saxony-Anhalt (1994–2002).
