I don't dip into Private Eye as often as I used to, but I started reading it in my teens and was a subscriber for most of my adult life. I suppose I still have a sentimental fondness for it even if I feel it's not what it used to be.
A lot of that fondness was always due to the writers. I used to idolise Paul Foot. I'd be a lot more critical of him now, because of some things he got badly wrong, and more particularly the stuff he turned a blind eye to in his SWP career, but Paul could be an absolute dog with a bone when he got started on a scandal.
Francis Wheen once did me a small kindness at a low point in my life, and I'll always remember him for that.
But the Eye's whole identity is based on it exposing the things powerful people don't want you to know. If there's been a huge scandal brewing in plain sight for years, and the Eye says nothing about it, and when they finally have to acknowledge it, it's with a whole lot of both-sidesing and complaining about the toxic debate, and doing a little spin for the Labour front bench... that tells you something.
I keep coming back to it being a boys' club. I just don't think this was seen as being a significant issue, or at least not significant enough to risk the flak. I suspect even Helen Lewis's very mild takes drew some eyerolls.
