Duff gave a group of Brussels journalists a copy of a letter he sent yesterday (3 March) to European Parliament President Jerzy Buzek, in which he calls for a revision of Article 48 of the Lisbon Treaty.
If Duff's proposal was to succeed, future EU treaty amendments could enter into force if a four-fifths majority of member countries ratify the treaty change, instead of all member countries as is currently the case. Before any treaty change, unanimity at an Intergovernmental conference (IGC) still remains essential.
