The National People's Party (NPP) today nominated late P A Sangma's youngest son Conrad K Sangma to contest for the May 16 by-poll in Tura parliamentary constituency.
The decision was taken at the party's central election committee meeting, party spokesperson James K Sangma said.
The ruling Congress has already nominated Chief Minister Mukul Sangma's wife and legislator Dikkanchi Shira to contest the by-poll.
The BJP has so far not decided on whether to field any candidate even as regional parties have decided not to put up any contestant.
The by-poll was necessitated following the death of Purno A Sangma.
