Graham, you are absolutely right about Mishal Husain, and I wrote to BBC World News to the same effect (with no reply, as expected). It is mere pretension and linguistic ignorance rather than the correctness she evidently assumes.

Let’s make a comparison: does frequent BBC broadcaster Agnes Poirier talk about Paris and France with the French pronunciations? No, she’s too sensible. She knows she’s speaking English, not French, and she uses the accepted English way to say those words.
