Zack Polanski, the Green Party leader in England and Wales, tells Nick Robinson that his rise to the leadership has been a 'whirlwind' and that becoming Prime Minister is now within his sights. He reflects on how he has sought to shape political debate in recent months and the role storytelling plays in his approach to leadership.

Polanski discusses his upbringing in a Jewish family and how his identity has influenced his politics, including his evolution into a prominent critic of Israel and his strong opposition to the war in Iran. He sets out his ambition to overhaul the current capitalist system through what he calls 'Zackonomics', a transformative economic vision.

He also addresses his earlier career as a hypnotherapist, admitting he now cringes at some past work, including taking part in a trial that aimed to help a woman increase her breast size.
