Congress president Rahul Gandhi on Wednesday held a 'Kisan Samriddhi Sankalp Rally' in Madhya Pradesh’s Mandsaur to mark the first anniversary of the farmers’ killings a year ago. Madhya Pradesh is slated to go to polls later this year and the Congress is making all-out efforts to make the rally big ahead of the Assembly elections. The Congress, which has been in the political wilderness for the past 15 years, is seeking to wrest power from the BJP in the state.
