With that enlargement, the Commission's membership increased to thirteen under the Ortoli Commission (the United Kingdom as a large member was granted two Commissioners), which dealt with the enlarged community during economic and international instability at that time.
O dată cu extinderea, Comisia a crescut la 13 membri sub Comisia Orteli (Regatul Unit a primit 2 locuri de comisar din cauza faptului că este un stat mare), care s-a confruntat cu instabilitatea internationala si economică din acea perioadă.
