I guess if Benn loses then that's it for him as far as leadership goes.
Will be interesting to see what the future brings for the likes of Livingstone, Galloway, Corbyn, Nellist and McDonnell in his TL.
Benn is still 62, so technically he might still have another run if he loses and there's another leadership election in the next couple of years.
Aye, they should be showing up in the coming terms of the TL, particularly the final four. Livingstone is a much less relevant character, having lost the first London Mayoral Election (1987) to the famous actor recruited as a candidate by the Tories.
