LG, I suspected it had been abolished but carefully said 'appears' to be in force because I looked in the criminal lawyers' 'bible' , Archbold's Criminal Pleading and Practice 2013, published a few weeks ago (lawyers think in the future, evidently) under blasphemy and could find no reference to it being abolished . Indeed, there were learned citations of fairly recent cases of Muslims being not protected by the law, it being only applicable to Christians, and references to Human Rights legislation !
Mind, it's not the first time Archbold has been misleading. Years ago,one of their specimen indictments was wrong, an error repeated so often in ensuing editions that, by the time anyone persuaded the authors to change it, it had become an accepted version!
