Pleading for a collective responsibility to strive to restore peace in Manipur, Tamil Nadu Chief Minister M K Stalin on Thursday said preventing Congress leader Rahul Gandhi from visiting the northeast Indian state is tantamount to obstructing the path to progress. In a tweet, the Chief Minister said, "It is our collective responsibility to work towards restoring peace in the lives of families in Manipur, considering ourselves as their extended family. Let political differences or any other barriers never hinder our efforts to bring tranquility into their lives."
