Bulgarian Progressive Line

The Bulgarian Progressive Line (Българска прогресивна линия, BPL) is a democratic socialist and left-wing political party in Bulgaria. It has been the successor of the Bulgarian Liberal Party.

History
The party was created in the winter of 2020–2021 by several progressive deputies of the National Assembly of Bulgaria who split from the Bulgarian Socialist Party. The BPL participated in the April 2021 Bulgarian parliamentary election but did not meet the electoral threshold. The party had 3,751 votes (0.15%).

In July 2021, the party entered the Left Union for a Clean and Holy Republic coalition with the Party of the Bulgarian Communists, the Left Alternative, the Socialist Party "Bulgarian Way", and the party Revival of the Fatherland.
