Lawyers to lodge appeal for Briton sentenced to hang for blasphemy in Pakistan Mohammad Asghar, who has a history of mental illness, was arrested in 2010 after a disgruntled tenant living in his property went to police with unsent letters allegedly written by Asghar in which he claimed to be the Prophet Mohammed. "He is not well and needs to be moved as soon as possible," he said, speaking on condition of anonymity, such is the sensitivity of blasphemy cases and fear of being targeted by violent extremists. We are concerned about his medication and the fact that he doesn't know whether he is getting the right drugs. The 69-year-old grandfather from Edinburgh was diagnosed with paranoid schizophrenia in 2010 before leaving the UK for Pakistan. British officials have visited Mr Asghar at Adiala high-security prison in Rawalpindi and raised the case with the Pakistani government. Islamabad called a moratorium on hanging in 2008 and most sentences are commuted to life in prison. Human rights campaigners and religious leaders have called for Mr Asghar to be allowed to return to the UK for treatment. Fred Drummond, director of the Evangelical Alliance of Scotland, added his voice to calls for the blasphemy law to be scrapped. "It is irrelevant whether Mr Asghar is a Christian or not," he said. What is relevant is concern over the misuse of the law which has been raised by numerous people including Pakistani politicians. Pakistan's hardline blasphemy laws are frequently used to settle personal scores or property disputes, according to critics.
