A voter turnout of 81.61 per cent was recorded in the previous assembly elections in 2018.

Technical glitches in EVM were reported from one polling station in Aizawl where Chief Minister Zoramthanga went to vote, another official said.

"The CM had, in the morning, gone to Ramhlun Venglai Primary School polling station, but the EVM was not working at that time. So, he went back home and came again at 9.40 am to exercise his franchise," she said.

State Congress president Lalsawta also cast his vote at a polling station in his Aizawl West-III constituency at 7.40 am.

Of the 1,276 polling stations across Mizoram, 149 are remote voting centres, and 30 along the inter-state and international borders have been declared critical and vulnerable.

The 510-km-long international border with Myanmar and the 318-km boundary with Bangladesh have been sealed ahead of the polling.

The MNF had won 26 of the 40 seats, securing two more in subsequent by-polls, while the opposition ZPM had won eight constituencies, relegating Congress, which had bagged five assembly segments, to third place.
