Madhya Pradesh Chief Minister Kamal Nath was among the early ones to cast his vote on Monday for the Lok Sabha polls on the state’s Chhindwara seat, where his son Nakul Nath is the Congress candidate.

A poll official said Nath would not be able to exercise his democratic right in the Chhindwara Assembly bypoll as he is a registered voter from Saunsar Assembly seat.Barring the Naxal-affected Baiher, Lanjhi and Paraswada Assembly segments under Balaghat parliamentary seat, polling would be held from 7 am to 6 pm, a poll official said.In the Naxal-affected areas, polling would be held from 7 am to 4 pm, he added.

A total of 108 candidates are in the fray in the six Lok Sabha seats, including maximum 26 in Sidhi, followed by Balaghat 23, Jabalpur 22, Chhindwara 14, Shahdol 13 and Mandla 10.Nine candidates are trying their luck in the Chhindwara Assembly bypoll.
