A couple of months old but perhaps still of interest: an interview in French with Egypt's last King, Fuad II. Also see my previous post on Fuad II at his sister's funeral in Egypt in 2009.
Even when interviewed by Arab media, as when he did an Al-Arabiyya interview one time, he always speaks in French. Of course he was only a month old when he left Egypt (his father abdicated to him, and a Regency Council ruled in his name for less than a year before the Republic was proclaimed, but the infant King was in Europe with his parents.) He may have little facility in Arabic.
