Overall, it is a question of striking the right balance – protecting what is good about the Union while preparing for the challenges ahead. I hope that, if the right approach is taken, it should prove possible to reach an outcome that will endure and stand the test of time and that the sense that the Union is constantly being modified and reconstructed will be at an end. The Union has been like a building site for 50 years and it is time that process was bedded down. The convention and the treaty that follows should do that.
