Since the presidential election would be held through secret voting, one should exercise their conscience to elect the right person, Singh told media persons here.
Stating that Sangma did not belong to any political party,
Singh said UPA candidate Pranab Mukherjee, on the other hand, belonged to a political party.
Singh, a close associate of late former Manipur deputy chief minister and senior Congress leader I Tompok Singh, said Sangma was qualified to represent India which needed a president to represent her voice with sagacity, understanding, cultural heritage and goodwill at home and abroad.
