What does the UK leaving the EU say about the strength of the organisation going forward? Can it perhaps accomplish more with a reluctant partner gone? Or is the ambition of ever-closer political and economic union doomed?
Owen Bennett Jones is in Brussels with a panel of European politicians and experts to reflect on the implications of the UK voting to leave the European Union.
On the panel: journalist Tom Nuttall, Lithuanian MEP Antanas Guoga and Rosa Balfour, senior fellow in the European Programme at the German Marshall Fund of the United States, and German MEP Hans-Olaf Henkel.
With contributions from former Belgian prime minister Guy Verhofstadt, Italian MEP Laura Ferrara, German MEP Beatrix von Storch,
