House of Commons abuse cases 'tolerated and concealed' per BBC News

This BBC report https://www.bbc.co.uk/news/uk-politics-45862741 on a report into House of Commons bullying runs thus, and I repeat it all below to prove a point:

'"Disturbing" cases of bullying and sexual harassment have "long been tolerated and concealed" in the House of Commons, according to a report.

The report, by Dame Laura Cox QC, said there was a culture of "deference, subservience, acquiescence and silence".

She said the procedures for protecting staff were inadequate and said "broad cultural change" was needed.

The inquiry was commissioned following a BBC investigation earlier this year.

Dame Laura described the House of Commons as a "stark reminder of how bad things used to be".

"Abusive conduct of this kind is pervasive and no workplace is immune, but the culture in which it has been able to take hold in the House of Commons and the ineffective mechanisms for dealing with it make this a particularly serious case," she said.'

Not a word about The Speaker's Office? That's odd as Guido Fawkes reports:

'Dame Laura Cox explicitly names the Speaker's Office as part of the "senior House administration" which must replaced in order for the bullying culture to be addressed, concluding:

"I find it difficult to envisage how the necessary changes can be successfully delivered, and the confidence of the staff restored, under the current senior House administration."'

So why are the BBC protecting John Bercow's office, and thus him, from being mentioned in their report? I think we all know why.
