What was it like writing the economic policy for the 2017 and 2019 Labour Party manifestos? And what must people thinking about a new party think about? In this episode a rare type of insight provides a somewhat novel understanding of party politics in discussions happening at the moment. And about how we should be thinking about economics in the context of our current situation. Mary Robertson, deeply and thoughtfully, describes the technicalities of economic policy, the theory and the wider vision and practicalities that are necessary, and talks with Tom about being involved as activists in one of the most poignant moments of Corbynism.
