Polly Toynbee welcomes Labour’s manifesto but says Jeremy Corbyn’s lack of credibility means people will never trust him, so it will never be implemented (12 May). Is it not the case that Corbyn was severely damaged by opposition from several of the heavyweights of his own party right from the outset of his leadership? Is it not the case that even now, if some of the most powerful people in the party were to back Corbyn and this manifesto, his chances in the election would be greatly enhanced? If they support the manifesto, they should do so.
