The quote I have seen from Cox is an admission that he made mistakes while working for Save the Children.
That is very different from admitting to inappropriate hehaviour, which he denies.
If yoy have a link where he admits inappropriate behaviour to this woman, I wilk gladly view it, and may change my view.
As it is, it just looks like trial by media based on unsubstantiated allegations, and his only real crime is that he is a bit of a gobby leftie.
