Sir David Clementi, the architect of reforms to the BBC's governance, is to be the broadcaster's new chairman, it has been reported.
Sir David, a former deputy governor of the Bank of England, will be the first person to hold the post that he recommended in his independent review unless the Prime Minister intervenes, according to ITV.
The Government accepted Sir David's recommendation that the BBC Trust should be scrapped and replaced by one board of mostly non-executive directors.
ITV said an official announcement was expected later this week.
In the report commissioned by former culture secretary John Whittingdale, Sir David also recommended that Ofcom should take over the role as the BBC's regulator.
The BBC Trust's current chairman, Rona Fairhead, decided to quit the role rather than apply to take the helm of the new board.
