PM Modi's mother Heeraben arrives to vote at a polling booth in Gandhinagar.  

The voting for the second and final phase of Gujarat assembly elections is underway today on 93 seats of North and Central Gujarat.

After an acrimonious campaign, around 2.22 crore voters would be exercising their franchise today to choose between the two main contenders, the BJP and the Congress.

A total of 851 candidates are in fray for the second phase. The first phase of voting, held on December 9, covered 89 seats of the 182-member House. The election is being seen as a "prestige battle" for Prime Minister Modi and a litmus test for the leadership of Congress president-elect Rahul Gandhi. In the 2012 assembly polls, the BJP had won 115 seats, while the Congress bagged 61. The counting of votes will be taken up on December 18.
