| Nine new member states, including Ukraine and Moldova, are lined up to join the EU, potentially taking the union from a club of 27 to more than 35. But not all existing members support the expansion, especially with the prospect of seeing their EU contributions increase to welcome poorer countries. Can the union transform internally to function as a group of more than 35? Or will the national politics of certain states further create division?
Join our expert panel, chaired by the Guardian’s Jon Henley, as they explore how the EU might handle its expansion, its importance to its geopolitical future, and how the elections of other member states could derail the process. |
