Jeremy Corbyn's mind must move in a parallel universe if he believes the Labour Party are authentically left-wing.
Many Labour members in the Parliamentary Labour Party, more than a few in the Scottish Parliament, and "fixers" like Alastair Campbell, Peter Mandelson, and John McTernan, can hardly be described as left-wing. Many of them are of the centre, which it can be argued, is well to the right of where it once was. Some are decidedly right-of-centre, to the right of say, Ken Clarke, and you have to wonder if they wouldn't be more at home in the Tory Party. I would suggest that Jeremy Corbyn and his supporters aside, it is the Labour Party who are a "poor imitation" of a left-wing party.
