PPP Chairman Bilawal Bhutto Zardari on Friday spoke with Amina Taseer, the widow of late Punjab governor Salman Taseer on his second death anniversary and shared her grief. He hoped they would resolve their differences for a democratic system where people would not be killed and violence would not be carried out to settle the differences. Bilawal Bhutto Zardari said Shair-e-Punjab Salman Taseer would always be remembered among the people and the party workers as a beacon of light and source of courage. His sacrifices would strengthen the will of masses to protect the nation from evil forces, he added.
