In a major blow to the Congress party, former Maharashtra chief minister and the senior leader Narayan Rane resigned from his post on Thursday. He is expected to join Bharatiya Janata Party (BJP) in the coming days.

Rane submitted his resignation to the Congress chief Sonia Gandhi at 2:30 pm. According to sources, Rane has also put a condition before BJP that both his sons be accommodated in the party.

Over the past few days, Rane had expressed his dissatisfaction with the party’s decision to exclude him from the list of candidates for the chief minister’s post when it was in power in the state.

“I had gone to Congress because I was assured that I will be made chief minister in six months,” he said.

The senior Congress leader also said he left the grand old party because it had not fulfilled any of the promises it made in the last 12 years.

“No Congress leader ever cared to know the reason for my discomfort,” he added.

Narayan Rane had joined the Congress in 2005 after being expelled from the Shiv Sena. He was the chief minister of Maharashtra for a period of nine months in 1999 after Manohar Joshi stepped down.
