“The decision to start the new scheme in August has not been easy but delaying the introduction has cost the BBC over £70 million and we cannot afford to delay any further.”

When asked about Mr Carson’s appointment, the spokeswoman said: “This is not a new role.
“Steve Carson is replacing the current Director of BBC Scotland who is retiring at the end of the year, so there is no additional cost to the organisation with this appointment.”
