To which court are ambassadors accredited in the UK?

Ambassadors in the UK are accredited to the Court of St James's, which refers to the official residence of the British monarch, located in St James's, London. This term has historical significance as it denotes the location where diplomatic representatives are formally received by the monarchy. The designation "Court of St James's" encapsulates the idea of the British royal court and indicates the ambassador's representation of their home country to the British sovereign. This system reflects the traditional relationship between diplomacy and the sovereign, emphasizing the importance of royal approval and recognition in international relations. Each ambassador serves as a liaison between their country and the UK, and being accredited to this court signifies their official status in diplomatic matters.

Other options, such as the Court of Westminster, Court of Buckingham, and Court of Kensington, do not serve as formal titles for where ambassadors are accredited, and they refer to different aspects of the British royal or governmental settings. For instance, the Palace of Buckingham is the official residence of the monarch but does not carry the designation used for diplomatic accreditation, while Westminster relates to the British Parliament and is not associated with foreign diplomatic matters. Therefore, the Court of St James's is the appropriate and historically recognized location for such accreditations.
