A leading lawyer and the editor of The Times have joined the panel that will appoint the members of the new press regulatory board. Lord Browne of Eaton-under-Heywood and journalist John Witherow are joined on the panel by the former editor-in-chief of the Manchester Evening News, Paul Horrocks, and the former chairwoman of the Commission for Social Care Inspection Dame Denise Platt. However, the Hacked Off campaign group says the appointments have failed to meet independence criteria set out by Lord Justice Leveson. Steve Hewlett asks Sir Hayden Phillips, the chairman of the appointment panel, about the measures in place to ensure the process is independent.

Steve Hewlett talks to chairman of DCD Media David Elstein, who launched Channel 5 as its Chief Executive in 1997, about the impact Mr Desmond has made, and about which players might be interested in buying the terrestrial broadcaster.
