Composition Parliamentary groups

After the elections, the parliamentary groups were formed in the Seimas, largely on the party lines: Lithuanian Farmers and Greens Union (LVŽSF), Social Democratic Party of Lithuania (LSDPF), Liberal Movement (LSF), Order and Justice (FTT), Electoral Action of the Poles in Lithuania (LLRAF), Homeland Union - Lithuanian Christian Democrats (TSLKDF) and the Mixed Group of Members of the Seimas (MSNG).

The term of the Seimas was noted for particularly significant shifts among parliamentary groups. Most notable examples were Social Democratic Party and Order and Justice parliamentary groups. The former had split into two separate parliamentary groups (and later, parties), while the latter (along with the party) completely disintegrated.

By the end of the term of the Seimas, the following parliamentary groups were active.
