Damian Green gets under John McDonnell’s skin by claiming he doesn’t understand how the government borrows money. This pointy fingered exchange was revealing:

Green: “You don’t understand capitalism.”

McDonnell: “You certainly do, don’t you.“

Worth watching to see the famous McDonnell space invasion, usually only experienced by Labour MPs and staff…
