It seems there’s a certain amount of musical chairs going on this summer in the digital departments of the UK’s news organisations.

paidContent:UK reports that Torsten de Riese, Guardian News & Media’s mobile business manager for the past seven months, is departing for a digital director role at CNBC.

Meanwhile, Telegraph Media Group head of mobile, Maani Safa, has left the publisher. According to NMA, Safa’s replacement is Mark Challinor.

The Guardian has also announced a series of moves amongst its multimedia and digital teams: in September head of audio Matt Wells will become blogs editor; while current news editor Stuart Millar will become web news editor, responsible for live and breaking news coverage on the website.
