In a letter to the members of the working committee of the CAB, Dalmiya said he had decided to resign due to what he alleged as "a pre-determined and vindictive attitude of the current regime of the BCCI".

Dalmiya, who had been expelled for life by the BCCI earlier this month, said he would continue to fight against "injustice" on his own accord saying, "I am sure my stand would be fully vindicated through the process of law in which I have full confidence."

He also promised to stage a comeback saying, "I am confident that I will fully regain the opportunity to continue to serve the game of cricket with full honour."

Dalmiya, who has been controlling the affairs of CAB for almost 25 years, also proposed that former BCCI president Biswanath Dutt would be the right person to head CAB in these difficult circumstances.

Dalmiya's resignation came ahead of this evening's crucial working committee meeting of the CAB, in which the issue of Dalmiya's expulsion for life by BCCI was to be taken up. (Agencies)
