Line 1:
In [[Sri Lanka]] a system that may be considered a variant of the [[Supplementary Vote]] (SV) is used to elect the [[President of Sri Lanka|president]]. Under the '''Sri Lankan form of the Supplementary Vote''' (Sri Lankan SV) each voter ranks from among the list of candidates a first, a second and a third preference. If no candidate receives an absolute majority of votes on the first count all but the two leading candidates are eliminated and the second and third preferences of those who voted for eliminated candidates are redistributed to help determine a winner.
 
The current Sri Lankan presidential voting system is sometimes described as a form of the Supplementary Vote and sometimes as a variant of [[Instant-runoff voting|Instant Run-off Voting]], but differs from both in important respects. It is identical to the Supplementary Vote except that voters are permitted to express three preferences rather than just two. It differs from [[Instant-runoff voting|Instant Run-off Voting]] in this limitation on preferences but also in that there are only two rounds of counting. It can also be considered a variant of [[Runoff voting|Run-off Voting]], in which both 'rounds' occur without the need for a second round.
 
Sri Lankan SV has been used for presidential elections there since [[1982]]. As of [[2004]] it has not been introduced elsewhere.
