Four-time Chief Minister Lal Thanhawla won from both Serchhip and Hrangturzo seats.
After facing debacle in four states, the Congress today received some cheer in Mizoram where it stormed back to power for a second consecutive term capturing 22 of the 40 seats, while leading in four.
Of the 25 results declared so far, the main opposition Mizo National Front (MNF) lagged far behind with three seats, the same number it had won in 2008.
Four times Chief Minister Lal Thanhawla won from both Serchhip and Hrangturzo seats. In Serchhip, he won by a margin of 734 votes defeating his nearest MNF rival Lalramzauva, who got 4,985 votes in a four-cornered contest.
In Hrangturzo, the Chief Minister defeated his Mizoram People's Conference (MPC) rival Lalthansanga by 1638 votes. Thanhawla received 5173 votes in a five-cornered contest.
Of the eleven ministers who contested, eight - R. Lalzirliana (Home), J. H. Rothuama (Cooperation), P.C. Zoram Sangliana (Transport), H. Rohluna (Forests), Lalrinliana Sailo (Health), Lalsawta (Education), Zodintluanga (Sports) and P. C. Lalthanliana (Social Welfare) - won.
Assembly Speaker R. Romawia won from the prestigious Aizawl North-I seat. Tourism Minister S Hiato, however, lost to the MNF's K Beichhua in Saiha.
Congress also bagged the Tuivawl, South Tuipui, Lunglei South, Palak, Champhai North, Lawngtlai West, Tuirial, Tawi and Tuichawng seats.
Lal Thanhawla said contrary to anti-incumbency playing a crucial role after completion of a five-year term, in Mizoram, "pro-incumbency worked in favour of the Congress." "I am going to form the next government in the state," he said.
The opposition MNF bagged the Saiha, Tuikum and Lawngtlai East seats.
Barring MNF, the two other constituents - MPC and Maraland Democratic Front - of the Mizoram Democratic Alliance, were yet to open their account until 6 pm.
A prominent loser was opposition Zoram Nationalist Party (ZNP) chief Lalduhawma, who lost both from Aizawl West-I and Kolasib. The party had two seats in the outgoing House.
