High-profile female personalities at the BBC have written an open letter to director general Tony Hall calling on him to act immediately to tackle the gender pay gap.
The letter follows the release of documents which revealed two-thirds of its stars earning more than £150,000 are male, with Chris Evans the top-paid on between £2.2m and £2.25m.
The One Show's Alex Jones, Antiques Roadshow's Fiona Bruce and Newsnight presenter Emily Maitlis, were among over 40 women who have written an open letter to the Director-General calling on him to "correct this disparity".
In the letter, the signatories say they will be "prepared to meet" Mr Hall "so that future generations of women do not face this kind of discrimination".
It reads: "The pay details released in the Annual report showed what many of us have suspected for many years...that women at the BBC are being paid less than men for the same work.
"Compared to many women and men, we are very well compensated and fortunate. However, this is an age of equality and the BBC is an organisation that prides itself on its values.
"You have said that you will 'sort' the gender pay gap by 2020, but the BBC has known about the pay disparity for years.
"We all want to go on the record to call upon you to act now."
The letter adds: "Beyond the list, there are so many other areas including production, engineering and support services and global, regional and local media where a pay gap has languished for too long.
"This is an opportunity for those of us with strong and loud voices to use them on behalf of all, and for an organisation that had to be pushed into transparency to do the right thing.
"We would be willing to meet you to discuss ways in which you can correct this disparity so that future generations of women do not face this kind of discrimination."
Strictly Come Dancing host and Radio 2 DJ Claudia Winkleman was revealed as the highest earning BBC female earning between £450,000 and £499,000. She was paid just a fifth of what Chris Evans collected.
