A former BBC journalist claims younger reporters were able to "gatekeep" trans stories and gender critical coverage was "censored".
Cath Leng, who worked for the broadcaster for 25 years, also alleged she was "forced out" two years ago over her gender-critical views.
Previously, former chief writer told The Times that younger reporters specialising in LGBT coverage acted as "gatekeepers" on transgender stories and were seen as "experts" on the topic by older editors.
She said: "These people were treated as experts simply because they were believers in the idea of gender identity."
Ms Leng further claimed to have seen a News at Ten editor asking a junior journalist what language to use when putting together a Pride story.
Speaking on GB News about her time at the BBC, she discussed how she started to pitch stories, liaising with colleagues across a number of different sections, including politics, health, education and sport.
"But none of it really got anywhere," she told GB News presenters Olivia Utley and Miriam Cates, when handling stories relating to matters of sex and gender.
"Some of were used as human shields. We raised these issues - nothing was done.

"Still now they're denying the institutional bias exists and this is a particular issue, specifically sex and gender. Very little has changed.
"They are the very definition of institutional bias because there are plenty of people who are questioning and are curious about this issue, but you can't. It's built into the way a story is covered.
"It's carved into the walls of BBC journalism on this issue."
The veteran BBC journalist further alleged editors had been "complicit" in censoring stories that were gender-critical of trans issues.

In response to her claims, a BBC spokeswoman said: "[The broadcaster] reports a wide range of views and perspectives in line with our editorial guidelines.
"We continually review our coverage to reflect new developments and since the period [Ms Leng] is describing we have updated the news style guide and shared new guidance.
"Where there have been concerns about particular stories, we have addressed them.
"Although we do not comment on individual staff members or former staff members, all news staff are required to comply with the BBC’s social media guidelines, and we take the appropriate action when these are breached."
The allegations come after a leaked internal memo compiled by Michael Prescott, a former external adviser to the BBC’s editorial standards committee, highlighted several alleged shortcomings in the broadcaster's coverage, sparking concerns of bias.
BBC director-general Tim Davie and CEO of News, Deborah Turness, both quit on Sunday amid growing uproar.
Mr Prescott claimed stories raising "difficult questions" about transgender issues were often overlooked, even when widely reported by other media.
He also alleged that some features presented the transgender experience in an overly one-sided manner, lacking sufficient balance and objectivity.
The memo also noted that the BBC failed to cover certain stories, including a case in which a group of nurses sued their employer for permitting biological males to use their changing room.
The document further claimed the corporation had edited a speech by Donald Trump broadcast in a Panorama show a week before the US election.

It was alleged that the BBC had spliced together two separate excerpts from one of President's speeches to make it appear he was tell supporters to "fight like hell" at the January 2021 Capitol Hill riot.
President Trump has threatened the corporation with a $1billion [around £759,750,000] law suit if it does not meet a list of demands.
As stated in a letter penned by the President's lawyer, Alejandro Brito, this includes "a full and fair retraction" of the documentary and "any and all other false, defamatory, disparaging, misleading, and inflammatory statements about President Trump in as conspicuous a manner as they were originally published", as well as an apology and compensation.
A BBC spokesman said: "We will review the letter and respond directly in due course."
The Prime Minister's official spokesman, who yesterday insisted the broadcaster was not corrupt or institutionally biased, has declined to comment on Mr Trump's threat to sue, saying "it’s clearly not for the Government to comment on any ongoing legal matters".
