What They Are Saying

A Weekend that was definitely not a Mistake! I greatly enjoyed the wonderfully warm atmosphere that blurred the boundaries between the audience and the speakers. A wonderful event and brilliant for everyone to share ideas and expertise in this relaxed atmosphere.

We’re delighted to have the Department of Political Economy (DPE), King’s College London, as our Academic Partner again.

Founded in 2010, King’s DPE is the only dedicated Department of Political Economy in the United Kingdom. In a world characterised by financial uncertainty, ecological insecurity, and value conflict, the links between political and economic processes are ever more apparent, and the need for a multifaceted appreciation of how they operate has never been greater.
