Tim Marshall

Foreign affairs journalist, writer and commentator Tim Marshall looks at the past and present to explain the fault lines that will shape our world in coming years.

Marshall says we are in a new era of tribalism and the walls are going up. Money, race, religion and politics divide us. He argues that Trump’s wall says as much about its divided past as it does about its future and that an explosive combination of politics and migration threatens liberal democracy.

Marshall is author of the international bestseller Prisoners of Geography. He is a former diplomatic editor and foreign affairs editor for Sky News and now edits the world affairs blog www.thewhatandthewhy.com
