Women at the BBC have told MPs they faced "veiled threats" while trying to raise the subject of equal pay.

More than 150 women have put forward written evidence to the Digital, Culture, Media and Sport Committee, ahead of a hearing on Wednesday.

Auditors PwC have separately reviewed the pay and diversity of presenters, correspondents and on-air talent.

The BBC's media editor Amol Rajan says the corporation is proposing a pay cap of £320,000 for its news presenters.

The change, following an outcry about the size of the salaries of the BBC's highest paid stars, will only affect a handful of people but forms part of a wider restructuring of pay of on-air staff.

Tuesday's announcement about on-air pay and Wednesday's committee session take place against the backdrop of a long-running debate about gender pay at the BBC, which began last summer after the corporation published its salaries for on-air staff earning more than £150,000.

BBC director general Tony Hall and Carrie Gracie, who quit as the BBC's China editor over "pay discrimination" this month, will be questioned by the committee of MPs.

The BBC's media editor says the proposed £320,000 cap has not yet been fully agreed or signed off and will apply only to on-air staff working full time.

It will affect presenters, editors and correspondents, who will be given time to respond to the proposals.

However, it is not clear whether on air-staff will be able to earn more from other BBC work, for instance on entertainment programmes.

Last week, six of the BBC's leading male presenters agreed to take pay cuts.

Speaking to BBC Radio 4's Today programme, Damian Collins, chair of the DCMS select committee, said the £320,000 pay cap didn't fully address his concerns.

"It actually affects a relatively small number of people," he said.

"If you look at the grievances that Carrie Gracie brought forward, saying she wasn't paid the same amount as other international editors at the BBC, this new proposed pay cap wouldn't have addressed that at all."

Collins also discussed the pay disparity for talent outside of news - in areas of entertainment and sport.

He said: "Many people would look at that and say, 'why is it that Gary Lineker is paid many multiples of what Clare Balding is paid?'.

"Many people would say she does a job of equal value, working on many different outlets for the BBC and covering a wide range of sports. And that's why this review must go much broader than that."

'No confidence'

The National Union of Journalists and the BBC Women group have criticised the BBC's record on equal pay ahead of the MPs' inquiry into the issue.

BBC Women, a group that represents female BBC journalists and producers, said it had "no confidence in the on-air review" because it had not been consulted and felt it had "been excluded from the process".

"We believe there is a wider culture of gender discrimination, which can be seen in patterns of promotion, especially after women take maternity leave."

They added: "While individual BBC managers have been supportive there is still a bunker mentality in some quarters and women have experienced veiled threats made against them when they raised the subject of equal pay."

The group included several individual testimonies in its evidence to MPs, including one from former BBC Scotland health correspondent, Eleanor Bradford.

Bradford said she discovered she "was one of the lowest-paid correspondents at BBC Scotland, despite regularly appearing on UK-wide news and delivering exclusive stories".

She said she regularly asked for a pay rise and eventually was given a £5,000 increase but it was not backdated and she remained about £10,000 below some male colleagues doing exactly the same job.

She subsequently left the BBC.

Bradford told BBC Radio 4 Today that she felt it was an "unconscious bias", but there were "efforts to change things" during her last couple of years with the BBC.

"I do hope that there will be change, but I think nevertheless the spotlight should be shown on this because I think the change isn't happening fast enough," she said.

Thirteen further cases have been put forward anonymously.

They include:

A TV news presenter who said she "had been sitting next to a man doing an identical job who was being paid tens of thousands of pounds more... I am told that we are now being paid at the same rate per day, but there is no transparency"

A BBC reporter who found her full time equivalent salary for making identical programmes was about half her male counterpart

A sports broadcaster who has worked for the BBC for almost 30 years, both as staff and freelance, who found her £500 pay on a flagship radio programme was less than half of the male presenter

A regional news presenter who after becoming aware that her male colleague's salary was a third more than the figure she had been offered was given a 5% increase

An award-winning broadcaster on a flagship arts programme said she found her male colleague was being paid 50% more per show. "When I asked for (the) pay gap to be corrected the line manager told me 'the BBC doesn't do equal pay', and that in raising the issue I was being 'aggressive'. I refused to back down and eventually was given the same rate as my male colleague and it was backdated".

'Help women'

A BBC spokesperson said: "We look forward to an informed debate at the select committee based on all the facts.

"The BBC is committed to equal pay, and we don't accept the assertion we have not been complying with the Equality Act, nor do we offer inferior contracts based on someone's gender or race.

"We want to help women progress in their career and have set out ambitious targets to close the gender pay gap, filled by women. We've also set out action to achieve them.

"We have already set out how we plan to deliver real pay transparency for our staff, and today we'll publish proposals to significantly change how we manage on-air pay so we have a clear, transparent and fair system for the future."

The spokesperson added that the corporation would "not getting in to debates at the moment on pay band levels".

Damian Collins MP, chair of the DCMS committee, said that the complaints from the BBC Women group and the NUJ included those about "unlawful pay disparities on grounds of race, discrimination against women returning to work after periods of maternity leave, and discrimination against part-time workers and/or those who request flexible working".

A report published in October found men working for the BBC earn an average of 9.3% more than women.

The figure covered all staff, on and off air, and was put down to the fact there are more men in senior jobs.

It compares with a UK average of 18%, and BBC director general Tony Hall said it showed the BBC was "in a better place than many organisations".

The BBC announced several reviews into the issue of pay.
