I've just had a Nasser with John McDonnell on Sweeney Chalks.

He's the most left-wing chancellor we never had and one who didn't tank the pound.

John told me how it felt to lose one of the most critical general elections in decades,

Find out what I think about that and the rest of our conversation exclusively on Global Player.

Look for Sweeney keeps talking.

I'll be joined by my producer, Helen Burke, for this no-nonsense debrief.
