Not necessarily - depending on how many seats Labour loses at the GE, the Corbyncentric wing (if you want to call them that) of the PLP is likely to be proportionally significant in and of itself (15%) to be able to get a candidate on the ballot. In other words more Corbyn supporting MPs are in very safe seats - itās more the centrist wing who risk getting shipped out in a Tory landslide.
So donāt put the house on a glorious victory for Chuka just yet.
