[Margaret Pilkington]

I really don't know Cashy, but leaders have to be capable of leading.....they have to have the gravitas that underlines their authority......and he hasn't got that skill.

If you know that you have taken on something which is far bigger than you have the ability to cope with then you do the moral thing and make way for someone who can do what you can't.

It may seem like betraying those Labour Party members which voted him into this post, but surely that is better than watching the party implode......with all the consequences that such an action has.
His holding on, makes the party unelectable. It makes it look ridiculous.
