Calling himself a Congress worker till his last breath, Chaturvedi alleged that a "handful of people in Mumbai and Nagpur" were engaged in weakening the party by helping communal forces.
The former minister said that these elements conspired to act against him in order to carry forward their ulterior motives.
Chaturvedi, who has been elected as MLA from Nagpur five times, added that he came to know about his expulsion from media reports and had received no official communication from the Maharshtra Pradesh Congress Committee.
He said that it was ironical that he, after over five decades in the party, was being expelled at a time when the Congress leadership was welcoming new entrants with open arms.
Chaturvedi said that he would continue to apprise the party high command of the "nefarious activities of the conspirators" who he alleged had damaged the credibility of the party.
