Citing his inability to continue amidst 'various pulls and pressures' within the organisation, senior journalist Rajat Sharma on Saturday resigned from the post of president of Delhi & Districts Cricket Association (DDCA). Relevantly, Sharma's nearly 20-month tenure was a tumultuous one with his public differences with general secretary Vinod Tihara, who enjoys a fair amount of support base in the organisation. 'The cricket administration here is full of pulls and pressures all the time. I feel that vested interests are always actively working against the interest of cricket,' Sharma said in a statement.
