ISLAMABAD - Former President Asif Ali Zardari on Tuesday said that the arrest of Altaf Hussain is a sensitive matter because he is a leader of a mainstream political party of Pakistan. "The UK is known for its rule of law as well as its traditions of protecting human rights," said the co-chairman PPP in a statement. Demanding complete justice, he said that process needs to be done in a transparent manner, protecting Hussain's fundamental rights to life, dignity and fair trial as well as fulfilling all international laws of human rights.
