BBC Audio and Music has undergone “significant cultural changes” according to an independent report following the measures indentified by the BBC Trust in the wake of Sachsgate.

The review conducted by former Ofcom partner Tim Suter and ex-Radio Authority chief executive Tony Stollerhas found the importance of compliance is now fully understood.

It was launched in the wake of Sachsgate, when Jonathan Ross and Russell Brand left offensive messages on the voicemail of veteran actor Andrew Sachs during a pre-recorded Radio 2 show in October 2008.

Systems are now in place which include monthly spot checks of shows and all “high risk” programmes listened to ahead of broadcast. Risk lists have also been formally created to highlight shows with potential issues.

But the report found the BBC has not scrapped any shows it should be making having deemed them too dangerous.

BBC Trustee Alison Hastings, member of the Trust’s Editorial Standards Committee, welcomed the changes made.

“The Trust expected to see real evidence of change – so I am pleased to see that this report concludes that this has been delivered and that it has not been at the expense of programme-making,” said Hastings.

The report recommended further regular compliance process checks and staff training to deal with emerging potential issues such as online distribution.
