Lalengmawia told PTI this evening that the re-poll was ordered after the decision was made by the Election Commission following complaints from a number of voters and the decision of the Commission came late this evening.
A polling official in the polling station allegedly told voters to push a particular button, the third one (that of the Congress candidate's) and the complaint was lodged to the state election department by the Zoram Nationalist Party (ZNP) after two women voters lodged a protest.
Candidates in the seat included the sitting legislator K Liantlinga of the ZNP, R Vanlalvena, former student leader, of the ruling Congress, who had contested and lost in 2008 state assembly polls and RK Lianzuala of the main opposition Mizo National Front (MNF), a well-known television personality.
