Sonia Gandhi's memoir Belonging has triggered a political debate in poll-bound Punjab, with Opposition parties questioning her account of two of the darkest chapters in the state's history: Operation Blue Star and the 1984 anti-Sikh violence.

With Punjab heading towards elections, has Belonging reopened old wounds and a political battle?
