Rane, who has made his displeasure known several times over the functioning of the state Congress leadership, is extremely upset since his son Nilesh lost from Ratnagiri- Sindhudurg Lok Sabha seat to Shiv Sena.
He stayed away from Cabinet meetings as well since Congress suffered a massive defeat, bagging only 2 out of total 27 seats it had contested in Maharashtra.
Rane has blamed Congress' alliance partner, the NCP for conspiring to defeat Congress candidates. He had tendered his resignation from the Cabinet on the day results were declared but Chief Minister Prithviraj Chavan turned it down.
During the campaign, Rane had lamented that Congress had not utilised his services properly.
