As UK citizens prepare to vote next week on whether to remain part of the European Union, what impact will a potential "Brexit" have on the global economy? In this week's UpFront, we ask Angel Gurria, the secretary-general of the Organisation of Economic Cooperation and Development, about the EU referendum and the OECD's 2016 Economic Survey on the US economy. This interview was recorded prior to the killing of British MP Jo Cox. In the Reality Check, we look at how economic sanctions often cause more harm than good. And in the Arena, we debate the pros and cons of Universal Basic Income with Swiss Senator Andrea Caroni and expert Dylan Matthews.
