Source: author’s own dataset of polls published by CBOS, IBRIS, IPSOS, Millward Brown (MB), TNS Polska (TNS; TNSTVP) and GFK.
Notes: The figure for Law and Justice (PiS) includes support for two minor parties, United Poland (SP) and Poland Together (PR), as these three parties have an agreement to run common lists and candidates. United Left (ZL) is an electoral coalition formed by the Democratic Left Alliance (SLD), Your Movement (TR) and other minor parties. Where pollsters have not asked specifically about support for ZL, an estimate has been derived by adding together support for SLD and TR.
