Candidates for each constituency are chosen by the political parties or stand as independents. Each constituency elects one MP under the first past the post system of election. Since Nepal uses a parallel voting system, voters cast another ballot to elect MPs through the party-list proportional representation. The current constitution specifies that 165 MPs are elected from the first past the post system and 110 MPs are elected through the party-list proportional representation system. Women should account for one third of total members elected from each party and if one-third percentage are not elected, the party that fails to ensure so shall have to elect one-third of total number as women through the party-list proportional representation.
