This is the sixth time, including two consecutive terms, that the Congress has come to power in the mountainous state, which shares borders with Myanmar and Bangladesh.
In the Nov 25 Mizoram assembly elections, results of which were declared Monday, the ruling Congress swept 33 of the 40 seats (one seat more than in the outgoing house), leaving five seats to the opposition Mizo National Front (MNF) and one for the Mizoram People's Conference (MPC).
The result of Lawngtlai East constituency was withheld because of defective electronic voting machines at one polling station.
Repolling at the Tialdawngilung polling station is being held Wednesday and counting of votes will be held Thursday.
