Who is really in charge? The people or the markets? 

In the first episode of Radical Thinking, a new series from the Guardian, senior economics commentator Aditya Chakrabortty speaks to the former Greek finance minister Yanis Varoufakis. 

In an extended interview, we hear what it was like during the Eurocrisis when he went head to head with those who wanted to stop his economic changes. And, what does he make of Andy Burnham's plans to 'rewire' the UK economy? 

Radical Thinking will be published every Saturday in the Politics Weekly feed
