Election Commission officials said campaigning can go on in adjoining areas of constituencies where campaigning has already ended.
"In such cases, a radius of 100 meters from the border of the constituency where campaigning has ended has to be kept sanitised from all political campaigning," officials said.
In Kolkata, there are seven seats in northern part - Chowringhee, Entally, Beleghata, Jorasanko, Shyampukur, Maniktala and Kashipur-Belgachhia - where campaigning ended at 6 PM yesterday for the third phase of assembly polls tomorrow.
