Entitled

What's in a title ?  Rhodri Talfan-Davies was called Executive Director at the BBC, seconded to look after AI, when he was asked to step up as Interim Director General until the arrival of Matt Brittin last month.

According to the main BBC Board pages, he's once again an 'Executive Director'. However, at a London conference yesterday, he was billed as 'Editorial Director'; that's also the title on his Linkedin Page.

Is this an early pointer to Deputy DG ?
