Voters in Puducherry will have to identify themselves on the basis of Electoral Photo Identity Cards before exercising their franchise for the April 13 Assembly poll. Chief Electoral Officer Belatee Pertin said in a release in Puducherry today that all voters have been covered under EPIC. With cent per cent coverage under EPIC and Photo Electoral Rolls voters should identify themselves only on the basis of EPIC cards and not through any other alternative documents, as per the order of the Election Commission. Puducherry and its outlying regions of Karaikal, Mahe and Yanam will have a one day poll on April 13.
