Electoral districts of Sri Lanka

The 1978 Constitution of Sri Lanka provides for the election of members of Parliament from 22 multi-member electoral districts through the proportional representation electoral system. All but two of the electoral districts are conterminous with their namesake administrative district. The two exceptions are Jaffna (which covers the administrative districts of Jaffna and Kilinochchi) and Vanni (which covers the administrative districts of Mannar, Mullaitivu and Vavuniya). The first general election which used these electoral districts was in 1989.
