Shed no tears for miss Abbott. A posturing "liberal", seeking celebrity status at the close of her political career.
I have no idea what Mr Corbyn was thinking of when he appointed her.

Abbott would be much more comfortable amongst the careerists and wet eyed "liberals" who compose the rump of the Parliamentary Party.

As I said already Mr Corbyn's mandate is from the rank and fie membership who know that electoral power is beyond them at present.
Mr Corbyns job is to educate and propose alternatives to global Capitalism, he has a strong political base of committed socialists, but against the whole of the media and with a Party of backstabbers he has no chance of power.....nor should he want it at this juncture.
