Mukhtar Ahmed Butt in his letter says Zardari was not in the picture on CoD and is, hence, not responsible for it. But Benazir Bhutto had signed CoD as the chairperson of PPP, not in her personal capacity. He says a Bhurban-like accord should again be attempted. My question is what would stop Zardari from backing out of that also? -KHURSHID ANWER, Lahore, via e-mail, January 25.
