The Nice treaty is designed to change how decisions are made in the EU in order to allow for enlargement. Ten countries from eastern and central Europe are due to complete negotiations to join Europe. Decisions in Europe are currently taken under a model that existed for the six original founding countries in 1957. This model must be modernised if the EU is to grow in size to become a community of 27 member states. If the decision-making changes are not implemented then log-jams will arise. The European Union's internal systems will simply not be able to cope under the existing arrangements.
