The BBC would be forced to name all stars earning over 150,000 pounds (USD 200,000) per year, extending transparency in a move designed to generate cost-savings for the institution.
The BBC's budget is in focus days after it lost one of its top shows, "The Great British Bake Off", which was bought by a commercial rival.

"By making the BBC more transparent, it will help deliver savings that can then be invested in even more great programmes," she added in a statement.

The broadcaster said it would not meet the financial demands of the private production company behind the programme.
