The Maharashtra Pradesh Congress Committee (MPCC), in a letter to Chaturvedi yesterday, said it had received complaints alleging that he supported rebel Congress leaders to defeat the party's official candidates in the civic polls.
A show-cause notice was issued to him but he didn't reply, said the letter.
Subsequently, the president of Nagpur District Congress Committee conducted an inquiry and "the report findings confirmed your involvement in promoting rebel Congress candidates" which led to the defeat of party-nominated candidates, the MPCC said.
Chaturvedi couldn't be contacted for a reaction.
