A native of the northern city of Toruń, the co-capital and assembly location of the Kuyavian-Pomeranian Voivodeship, Grażyna Ciemniak initially gained her Senate seat in the 1993 parliamentary election. While not in the Sejm during its 1997–2001 term, she served, in 1998–2001, as Deputy President of Bydgoszcz, a position subject to election by the Bydgoszcz City Council.
In 2001 Polish parliamentary election, she campaigned for the Sejm IV term from Bydgoszcz district 4 as candidate from the Democratic Left Alliance-Labor Union (SLD-UP) list[1] and was elected with 8,212 votes.[2] Between April 2003 (signed of Treaty of Accession 2003) and 31 April 2004, Grażyna Ciemniak was an observer representing the Sejm in the European Parliament.[3] Between 1 May and 19 July she served as a non-elected member of European Parliament V.[4]
In 2004 European Parliament election she was a candidate of Democratic Left Alliance-Labor Union from Kuyavian-Pomeranian constituency. She polled an insufficient 9,001 votes[5] and was not elected.
In 2005 parliamentary election she was started to the Sejm V Term from 4 Bydgoszcz district. She polled 3,807 votes and was second on the Democratic Left Alliance (SLD) list[6] for the Sejm term which ended in 2007.
