Veteran Congress leader and former Madhya Pradesh Chief Minister Kamal Nath is likely to mediate in the crisis in Rajasthan and will meet party chief Sonia Gandhi, sources told NDTV. Ninety-two MLAs in Rajasthan threatened to resign yesterday, saying they want Ashok Gehlot -- front-runner for the post of the Congress national president -- to retain the post of the Chief Minister. The possibility was negated by Rahul Gandhi, who said the party will stick to the "One man one post" rule.
