Will Tim Davie’s resignation be enough to restore public trust in the BBC?

Senior insiders admit concern about big editorial errors and fear attacks are part of ongoing campaign to undermine the broadcaster

There is a joke regularly deployed by BBC staff that deputy heads must roll" over big mistakes because they rarely appear to have any impact on those at the top of the organisation. That all changed on Sunday, when Tim Davie and Deborah Turness both quit their jobs.
