Social media users flocked to voice their overwhelmingly negative opinions of Batmanghelidjh and Yentob's performance at the select committee hearing, which was looking into the reasons why Kids Company had folded.
Charity sector commentators were equally scathing, and said they hoped the public mauling would not damage the reputation of the broader sector.
Before the hearing, PR professionals had suggested that the charismatic and colourful Batmanghelidjh would have been wise to "tone it down" and "show some real humility" when answering questions.
While Batmanghelidjh has been given some media advice by one PR firm in recent weeks, her response to one question from committee chair Bernard Jenkin, a Conservative MP, was seen as particularly ill-judged.
Batmanghelidjh's performance earned little praise.
No matter what Batman is asked, she answers with a completely irrelevant speech. #kidscompany— Jim Edwards (@Jim_Edwards) October 15, 2015

Jenkin began the event by saying that it should not become a "show trial".

Over the three hour-long hearing, varied and sometimes puzzling information emerged about Kids Company's spending.

Charity sector professionals watching the hearing couldn't quite believe what they were witnessing:

so much to pick over from this morning, that I fear there is much, much more to come - car crash in extremely slow motion #kidscompany— Nick Temple (@nicktemple1) October 15, 2015
Not to mention a quite terrible display from CB & AY - who briefed /prepped them? Anyone? Unbelievable #kidscompany— Nick Temple (@nicktemple1) October 15, 2015
Both Temple and Wilding said they feared the charity sector as a whole might face a broader backlash.
Even more depressing, you can bet every sector commentator is already drafting the "things we learned" article / blog post now #kidscompany— Nick Temple (@nicktemple1) October 15, 2015
Nonetheless, journalists have been given plenty to work with by the hearing:
There are so many news stories out of this Kids Co hearing we might just put a headline on the transcript. Extraordinary.— Stuart Millar (@stuartmillar159) October 15, 2015
