Radio 4's Sunday is running a short series at the moment looking at the persecution of Christians around the world.
So far they've looked at North Korea and Eritrea, both authoritarian states (one communist, the other secular).
Of the top 20 countries judged to be the worst in which to be a Christian, however, 14 out of 20 are Muslim-majority countries (unlike North Korea and Eritrea) so, presumably, next week's essay will be about one of those. (Iran maybe? Or Pakistan?).
After all, Sunday wouldn't want to give listeners the wrong impression, would it, about where the main danger to Christians is coming from at the moment?
