State Congress chief Ashok Chavan had asked the Gondia district Congress president Purshottam Katare to give a written explanation within three days, party sources said.
In Gondia, the NCP recently emerged winner 20 seats in the 53-member Zilla Parishad. The BJP bagged 17 and Congress 16 seats. However, Congress had a post-poll alliance with BJP and bagged the ZP president's post while the saffron party got the vice president's post, leaving NCP out of power.
The letter issued by state Congress to the Gondia unit said it had taken a serious view of the district unit's action, and after receiving the clarification, Chavan will hold another meeting and send a report to the high command.
A Congress office-bearer here said that though the alliance with saffron party was embarrassing, the state leadership must do a tight-rope walk while taking action.
Asked if the district unit would be asked to break the alliance with BJP, the leader said the party was aware of the fact that any decision would have to be ultimately implemented at the ground level. "Views of the 16 Zilla Parishad members can't be disregarded," he said.
