Again, I'm struggling here, because as in our previous discussions, you don't seem to be replying to the words I've written. I said: 'Corbyn is not co-leader', and you reply, 'Where does it say [Sultana] is not co-leader?'
As often with supporters of Corbyn, I find your willingness to read whatever you want into his sayings a source of frustration. If he is co-leading this new foundation, or party, or whatever it is, why did he not just say so? Why use the passive voice? I suspect the reason he writes these convoluted non-statements - who is 'us'? What is a 'new kind' of party? Who is shaping it? Amongst whom are discussions ongoing? - is precisely to avoid anyone pinning him down to anything concrete.
Again, the case is the exact opposite of the one you're making. 'When he starts assembling a new party he knows the news will leak' - so why did he not have a clear statement ready? Because he has nothing to say. He's 'playing open card' but he's incapable of even saying who is putting the party together, or confirming if he's in some sort of leadeship role. Why? Because he has nothing to say.
Frankly, I think Sultana knows that waiting for Corbyn to commit to anything will take forever. She was probably trying to bounce him into taking an actual position and, as most people have found, he just doesn't want to. Good for her for trying something big but, for her sake, I hope this shows her it's time to move on from the guy.
You have got to stop putting this dim, narcissistic man on a pedestal and taking your fanfic about him as reality. The reason he has said nothing concrete is that he has nothing to say.
