The Lord High Commissioner to the General Assembly
The Lord High Commissioner to the General Assembly of the Church of Scotland is appointed by the Crown. The Lord High Commissioner takes up residence for the week of the Assembly in the Palace of Holyroodhouse.
The same style is used for men and women when addressing the holder of this post. A letter should begin ‘Your Grace’ and end ‘I have the honour to remain, Your Grace’s most devoted and obedient servant’. The envelope is addressed to ‘His/Her Grace the Lord High Commissioner’. Verbal address is ‘Your Grace’, while the description in conversation is ‘The Lord High Commissioner’.
When The Princess Royal was appointed, she was styled as ‘Her Grace’ for the duration rather than her normal dynastic style ‘Her Royal Highness’ because the Lord High Commissioner is ranked higher in the order of precedence.
If a woman is appointed to the office, the alternative title ‘Her Majesty’s High Commissioner’ may be used.
