In February 1945, the AVNOJ was expanded to include members drawn from Serbia, Montenegro and Kosovo-Metohija, areas that were not represented at its second session. The move came after a suggestion from the Allies. The AVNOJ was once more expanded in late March to include 54 members of the pre-war Yugoslav Parliament as required by the Tito–Šubašić Agreement. At the Yalta Conference, Churchill and Stalin discussed the decisions made by the AVNOJ; they agreed to demand ratification of all previous decisions taken by the AVNOJ by the future Yugoslav Constitutional Assembly.
