Jagdale said he quit from his post as he was deeply hurt by the current crisis that has hit Indian cricket.
"Yes, that's true, I have resigned from the post of honorary secretary of BCCI," Jagdale said.
"I don't want to comment further but I am deeply hurt by the recent developments in Indian cricket. I thought it's better to get out so that some new faces come in and deal with it in a better way," he added.
"I can't comment about the resignation letter I have written to the President. It's proper to inform the President and I have done that.

Jagdale said he would no longer be part of the three-man inquiry commission set up by the BCCI to go into allegations against Srinivasan's son-in-low and CSK Team Principal Gurunath Meiyappan, who was arrested on charges of betting in IPL, and Rajasthan Royals franchise.
"I have already expressed my inability to be part of the commission," Jagdale said.
"I can't comment on whether other BCCI members would follow suit and resign."
Shirke also confirmed his resignation.
"I have spelt out my reasons (for resignation). I don't want to comment any further. I have already spoken to the media at length," Srirke said.
Shirke said he was not cajoled by Srinivasan not to quit.
Buckling under relentless pressure on him to quit, Srinivasan today convened an emergency meeting of the Board's all-powerful working committee on June 8 to discuss the current crisis arising out of betting and spot-fixing in IPL.
The beleaguered President's decision came after three important members called him up to convene such a meeting and asked him to announce it by the evening in what is seen as the first step towards possibly ousting him.
