Seating Plans for Royal Guests
When The Queen attends a function (official or private) the host always surrenders his place to HM, he himself being seated on The Queen's right.
Other members of the royal family are given special precedence before all non-royal guests.
The husband of a lady member of the royal family is accorded precedence immediately after her when both attend a function. If he attends alone, he retains his own precedence.
The Suite in attendance upon a member of the royal family should be placed reasonably near to him or her.
When the principal guest is The Queen it should be borne in mind that some or all of the following, and their spouses, should be invited to attend:-
The Lord-Lieutenant of the County
The Lord Mayor, Lord Provost, Mayor, Provost, Chairman of the City/Borough/District
The High Sheriff of the County
The Chairman of the County Council
