Convergence and Union
BNG lost its single Member of the European Parliament, Camilo Nogueira, in the 2004 European Parliament election. However, BNG's interests have continued to be represented thanks to alliances established with other parties such as the Basque Nationalist Party and the Catalan Convergence and Union. BNG maintains regular contact with its European group, the European Greens–European Free Alliance, through a permanent representative in the chamber.
