It needs to be recalled that despite its much-touted editorial independence, the British Broadcasting Corporation (BBC) has not exonerated itself from an accusation that it aired a sham request from an Argentine mother in order to appease the government of Margret Thatcher during the Falkland War (Joweth & O’Donnell, 1999, p. 296).
Jowett, G. & O’Donnell, V. (1999). Propaganda and persuasion. London:
