John Butt, a Cambridge University chaplain has established a radio station in Pakistan through which he tries to counter extremist teachings. Having first traveled to the region in 1969 and converted to Islam soon after, he is now based in both Cambridge and the Pakistani Swat valley. This is exactly the region where the Taliban have recently been allowed to introduce Sharia law, who also depend on radio broadcasting to disseminate their ideology. Mr. Butt, in return, offers a station that he describes as a local version of BBC Radio’s Five Live, dealing with current affairs, discussions and moderate interpretations of the Koran. With the tensions rising, he at least hopes to make “a start on making a difference”.
