The BBC is coming under pressure from politicians and other media outlets over its use of the term ‘Islamic State’.

Earlier this week, the Prime Minister criticised the corporation for using the term – rather than ISIS or ISIL, both of which are acronyms which include the offending term – and the director general was sent a letter signed by more than 120 MPs asking it to use the term “Daesh”.

Director general Tony Hall responded with a letter saying that using Daesh "would not preserve the BBC's impartiality”.
