The BSW currently has one member in Berlin’s House of Representatives. The party’s full name is “Alliance Sahra Wagenknecht – Reason and Justice” (“Bündnis Sahra Wagenknecht – Vernunft und Gerechtigkeit”). The name points to the party’s founder, Sahra Wagenknecht, who was for many years an important politician in Die Linke (The Left). In 2023, Wagenknecht and several other politicians from Die Linke left the party and founded the BSW. One of the reasons for this was disagreements in areas such as migration policy. On these socio-political issues, the BSW is more conservative than Die Linke.

At present, Alexander King is the BSW’s only member in the Berlin House of Representatives. He was elected as a member of parliament for the Left Party and later joined the BSW. King is also the BSW Berlin’s lead candidate for the upcoming House of Representatives election.
