Mark Byford will be responsible for a new BBC complaints system

He will become responsible for the enhanced complaints operation, following a BBC review of procedures.

Mr Byford said he was proud and privileged, adding: "I will strive to promote high standards, quality and the upholding of the BBC's values."

A new director of World Service will be appointed once he assumes his new role.

Programming issues

Mr Byford will also deputise for the BBC's director general Greg Dyke in his absence.

Mr Dyke said: "Anyone who knows Mark understands he is passionate about public service broadcasting and the BBC's role in the UK and around the world."

A new post of controller of complaints has been created to deal with issues raised after programmes have been broadcast.

The BBC's complaints procedure came under scrutiny during the Hutton Inquiry into the death of government weapons inspector Dr David Kelly.

A review into the complaints process had started before the inquiry opened and the new roles are part of the result.

Mr Dyke said: "As a result of the review we have decided to make a number of internal changes to modernise the complaints system and strengthen our post broadcast compliance procedures.

"The most important of these is the appointment of a deputy director general who will take overall responsibility for this area."

The BBC's editorial policy department, which deals with programming issues before they are broadcast, will report directly to Mr Byford.
