During the reign of King Otto, Moraitinis was a staunch member of the French Party. He served as the Caretaker Prime Minister of Greece (in his capacity as President of the National Assembly) for a few days in February 1863 during the period between the coup d'état against King Otto and the arrival of the new Danish-born Prince William, who would be known in Greece as King George I. Moraitinis was made Caretaker Prime Minister a second time for a little over a month in 1868 (in his capacity as President of the Court of Cassation). He died in Athens 1875.
