Jagmohan Dalmiya has resigned as president of the Asian Cricket Council and the Afro-Asian Cricket Cooperation.
He tendered his resignation from both the positions with immediate effect.
In a letter to BCCI president Sharad Pawar late last evening, Dalmiya said: "I had the privilege of being the president of the Asian Cricket Council from 2001-02 and the president of the Afro-Asian Cricket Cooperation from 2004-05. I was, in fact, the first president of the AACC to be elected unanimously.
"In view of the recent changes in the Board of Control for Cricket in India, however, I feel that it is only appropriate that I tender my resignation with immediate effect from both the positions.
"Nonetheless, I can assure you of my full support and cooperation as and when required on any matter concerning Indian or international cricket," the letter, a copy of which was released to the press in Kolkata, said.
