Digvijaya Singh, senior Congressman who is entering the party's presidential race, today indicated that his move was a spur-of-the-moment decision, made after it became clear that Rajasthan Chief Minister Ashok Gehlot's candidature got scuttled by the rebellion of his loyalist MLAs. If elected, he would carry out the party's decisions, as happens in a democratic system, Mr Singh said. A good leader is "not a dictator" but the "first among equals", he pointed out. "When the field is clear, I thought why not?" he told NDTV in an exclusive interview.
