Arancha Gonzalez Laya has had top jobs in the field of international trade at the European Commission, the World Trade Organization, and at the United Nations.

She is now the Dean of the school of politics and international studies at Sciences Po university in Paris – and the first woman to lead that school. She spoke to FRANCE 24 about the economic challenges facing Europe.
