I agree that this needs to be debated, starting with the cost of renationalising.
I read that the cost could be c. £200bn. Now I'd love to see them back in public hands but feel that we have greater current priorities e.g. NHS, social care, climate change, cost of living, etc.
I see renationalisation as a project for a second term Labour or coalition government. Far too much mess left by the Tories to sort out first.
