Parliament met for the first time since 1940 on 19 September 1944 in which Pierlot presented a summary of the government's actions in Britain during the occupation. One of the first acts of the government was to make Prince Charles, Leopold's brother, the prince regent on 20 September. On 26 September, a new liberation government of national unity was created. Because of a shortage of candidates, Pierlot continued to head it. The new government included members of the Communist Party of Belgium (PCB-KPB) for the first time. It presided over the eventual liberation of all of Belgium, delayed by a German offensive in the Ardennes in the winter of 1944. The government was weakened by continued problems with the national food supply in the winter of 1944 which caused popular discontent.
