King Charles hosts reception for nurses and midwives on his 75th birthday at Buckingham Palace.

Later on Tuesday afternoon, King Charles stepped out solo to host a reception celebrating midwives and nurses working in the U.K. at Buckingham Palace. The event was timed to the 75th anniversary of the National Health Service (NHS) this year. The reception welcomed about 400 nurses and midwives from diverse backgrounds and cultures, plus some of the 150,000 nurses and midwives from countries including India, the Philippines, Poland and Kenya who are currently working in the U.K., as well as reps from the International Nursing and Midwifery Associations.
When the time came to state Charles’ name, the group sang “Happy birthday, Your Majesty,” using thecorrect formal addressfor the monarch. King Charles raised his eyebrows at the “Your Majesty” mention, in what appeared to be a self-deprecating reaction to his royal role as sovereign.

According to the royal family’sofficial website, which has yet to be updated in full following the death ofQueen Elizabethin September 2022, “there are no obligatory codes of behaviour when meeting The Queen or a member of the Royal Family.” The Royal.UK website outlines that the traditional form is a neck bow from the head for men and a small curtsy for women, though some people prefer to simply shake hands.

As for greetings, Royal U.K. states, “On presentation to The Queen, the correct formal address is ‘Your Majesty’ and subsequently ‘Ma’am,’ pronounced with a short ‘a,’ as in ‘jam’. "
While King Charles would be referred to as “Sir” on second reference as a male member of the royal family, the “Your Majesty” title can also be used. It would also be appropriate to call Queen Camilla “Your Majesty” because she is the Queen.
Meanwhile, royal family members like Prince William and Princess Kate should technically be addressed as “Your Royal Highness” and subsequently “Sir” or “Ma’am” from there, the royal family website states.
