The Treaty of Lisbon

After the treaty intended to create a consolidated constitution for the European Union was not ratified, the existing EU treaties were amended and expanded. The institutional changes provided for in the original treaty were, however, carried over. This resulted in the Treaty of Lisbon, which also regulates the withdrawal of member states. The United Kingdom chose to withdraw from the EU on 31 January 2020.
