A new constitution was granted in 1947, restoring self-government and reestablishing the position of Prime Minister. At this point the British Institute moved to nearby Casa Bolino. The auberge was once again used as the OPM, with Paul Boffa being the first Prime Minister to use it as his office. On 16 January 1951, Prime Minister George Borg Olivier presented a small bronze model of Les Gavroches, created by artist Antonio Sciortino, to Princess Elizabeth (now Queen Elizabeth II) in a ceremony held at the building. The islands became independent as the State of Malta in 1964, and the independence was drafted on a table which still remains in the auberge today.
