Emily Bell is wrong to refer to issues of territory and boundary disputes in her account of the BBC Trust’s conclusions on executive proposals for 6 Music or other services (‘The BBC should call the shots’ Broadcast 16.7.10).

The BBC Charter explicitly requires the BBC Trust to oversee services.

This covers formal engagement through processes such as public value tests on executive proposals to make any significant change to the public services, including introducing a new service or closing a service.

It also covers more general Trust oversight of services through the issue, monitoring and review of service licences on a continuing basis.

This framework is well established and understood within the BBC as an integral part of the Trust’s role in looking after the interests of licence-fee payers.

It does not cut across the day-to-day editorial control that is rightly the responsibility of the director-general.
