In 2016, the branch of the Order led by the Duke of Castro was involved in controversy over the election of Patricia Scotland as Commonwealth Secretary-General. It was alleged that Scotland used the Order's awards to influence votes in her favour through reciprocal exchanges of honours. Investigations resulted in a knighthood granted to the Duke of Castro by the Governor General of Antigua being revoked. Attempted reconciliation On 24 January 2014, the day before the Blessed Beatification of the Venerable Servant of God Princess Maria Cristina of Savoy (later Queen Maria Cristina, Queen Consort of the Two Sicilies), the two disputed heads of the house: Prince Pedro, Duke of Noto (on behalf of his father Prince Carlos, Duke of Calabria) and Prince Carlo, Duke of Castro signed an "Act of Reconciliation" at Naples' Excelsior Hotel. This act appeared to have ended the longstanding differences over the titles used by the two branches of the House of the Two Sicilies. The signing of the act of reconciliation was done in the presence of the Duchesses of Noto and Castro, the Duke of Noto's mother, the Duchess of Calabria, the Duke of Noto's sisters, Maria and Inés, and their husbands, Archduke Simeon and Michele Carrelli Palombi, their aunt, Princess Teresa, Marchioness of Laserna, the Duke of Castro's sister, Princess Napoleon, Prince Casimiro of Bourbon-Two Sicilies and his wife Princess Margherita, and the Duke of Braganza. Owing to his state of health, the Infante Don Carlos, Duke of Calabria was unable to attend the ceremony. The Act stated that the two branches will recognize each other's titles for the present holders and their successors; the titles of the senior, Spanish line, being Duke of Calabria, Duke of Noto and Duke of Capua, and of the junior line, being Duke of Castro and Duchess of Palermo and Duchess of Capri which were accorded to the Duke and Duchess of Castro's two daughters. The final intention was to work towards a future where the two branches might co-operate together (although the revival of the Order of Francis I has never been accepted by the senior, Spanish line.) Renewed schism In May 2016 Prince Carlo unilaterally renounced the agreement and subsequently conferred the titles of Duchess of Calabria and Duchess of Noto on his daughters, declaring the former to be the heiress to the headship of the Royal House and the Constantinian Grand Mastership.
