"I am of the opinion that India should have at least 50 states like the United States of America," Sangma said Monday night.
UPA should carve out Telangana and Vidarbha states and set up a second State Reorganisation Commission to carry out scientific study over demands for new states like Bundelkhand, Harit Pradesh and other regions, he said.
Recalling the one-man committee headed by him to study the case of Vidarbha region, Sangma said he had duly recommended the creation of the new state and the then Prime Minister Rajiv Gandhi was about to make an announcement before the general elections but somehow, he was advised by some others not to do so in a hurry.
Sangma made an observation that during the period that a whopping Rs 700 crores was paid as cotton subsidy from the state exchequer which could upset the economics of Vidarbha. It was an apprehension at that time, he said.
Sangma, who founded the National People's Party earlier this year, has been consolidating his base among the tribals in Madhya Pradesh, Chhattisgarh, Rajasthan, Jharkhand and Bihar.
He is initially concentrating on states which are going to polls later this year, including Madhya Pradesh, Chhattisgarh and Rajasthan.
To get status of a national party, his party would field candidates during the assembly polls, the leader said.
Sangma was in Madhya Pradesh’s Chhindwara district on Monday to broker peace among three warring factions of the tribal-dominated Gondwana party to unitedly put up a fight in the elections scheduled there around the year end.
