The 1978 Constitution of Sri Lanka introduced the proportional representation electoral system for electing members of Parliament. The existing 160 mainly single-member electoral districts were replaced with 22 multi-member electoral districts. Biyagama electoral district was replaced by the Gampaha multi-member electoral district at the 1989 general elections, the first under the proportional representation system.
