The association confirmed the development through a tweet which read, “@RajatSharmaLive has tendered his resignation from the post of President, DDCA with immediate effect and forwarded it to the Apex Council.”
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.
Sharma had joined cricket administration after receiving active backing from former finance minister late Arun Jaitley.
Many DDCA insiders believe that Sharma lost ground once Jaitley was no more as the late former finance minister was the binding force for all the different factions.
Sharma was appointed as DDCA President in July 2018, beating World Cup winning former Indian cricketer Madan Lal to the post. His group had also managed to win all 12 seats in the DDCA elections.
