Women especially have not had enough role models at the top of the industry – and the few that have been prominent (there is just one at the top table) have not been diverse enough. That means those in my generation have seen only one type of successful female, which not everyone wants to emulate.
Women coming up behind us, should have more heroes to point to so they can pick and choose qualities they like most - just as men do.
Also, while Walker was a politically palatable choice in the aftermath of the Libor scandal, he has failed to rescue the bank's reputation or properly manage and control Anthony Jenkins, the CEO.

So, what is it about Fairhead that would make this mess look that bit tidier? Apart from her obvious credentials – simply being a woman will give her a different take in a cultural environment where group-think has allowed a litany of bad behavior to flourish. This role shouldn't be passed on to another pale-male-and-stale member of the old boys club. It needs a new approach, to match its new aspirations. Let's have a bit of the Carolyn McCall touch – after all, her decision to change focus from cost-cutting to customer service at EasyJet has done wonders for the airline.
The real hurdle would probably be whether Fairhead would even take the role, which could prove to be a poisoned chalice and has already been turned down by Sir Mike Rake.
