The debate which has been developing recently has thrown up four key issues: the date for the conclusion of negotiations, the accession date, the order in which the new countries are to join the Union and the transitional periods.
I den debat, der har fundet sted i den sidste tid, er der fire nøglespørgsmål, nemlig datoen for forhandlingernes afslutning, tiltrædelsesdatoen, de nye landes optagelsesrækkefølge og overgangsperioden.
