1998 By-elections
Bihar
10 seats contested
Only the by-polled seats, not the whole assembly. By-elections held in Bihar during 1998 — 10 seats were contested, not the full assembly. Results are shown as a table: a map of a handful of seats would leave the rest of the state blank, which reads as "no result" rather than "not contested". Seat shares below are of the seats contested here, not of the assembly.
