According to Ambassador to the Holy See, Nigel Baker:
On 8 January, with the gracious permission of Her Majesty The Queen, I laid a wreath at the tomb in the crypt of St Peter’s Basilica of James Francis Edward Stuart, 250 years after his burial there. The message on the wreath was very simple: “In memoriam – James Francis Edward Stuart – ‘The Chevalier’ – 1688-1766”.
In his lifetime, successive Popes always recognised him as King. However, significantly, Clement XIII did not extend that recognition to his sons, in tacit and later explicit recognition of the Hanoverian succession.
