Polly Toynbee, discusses Richard Murphy, author of the forthcoming book, 'The Courageous State'

"Since the 2008 crash conventional economists have run out of ideas.

But Richard Murphy abounds with them.

He writes with electric clarity about what went wrong and what could be done to put things right.

He is a new economic thinker, no mere theoretician but guided by a sharp and practical accountant's eye.

He knows where the money is hidden, who has it and how to release it.

Murphy is the closest thing to a one man think tank and he is as courageous as he says our politicians should be."

Polly Toynbee is a columnist for the Guardian. She was formerly BBC social affairs editor, columnist and associate editor of the Independent.
