Senior Congress leader P. Chidambaram on Wednesday said he would like to see a 15-year tenure of his party in Madhya Pradesh following the assembly election in which all three top party leaders from the state - Digvijaya Singh, Kamal Nath and Jyotraditya Scindia can become Chief Ministers.Asked about who will be the CM candidate for the party in Madhya Pradesh, he said: "I am not competent to answer the question. Whether the Congress would project a face or not is a decision based on states-specific condition."We have gone into elections in Punjab projecting a face in as Amarinder Singh. We have gone into elections not projecting a face."Asked which of the three leaders would be top contenders as the party's Chief Ministerial candidate, he said: "I don't think there is any fixed rule on that. If the Congress decides to project a face, I am sure they will project a good face from MP." Asked about his personal choice, he said: "Well.. all of them are my friends. I would like a 15-year tenure, so three of them can be the Chief Ministers."
