I was struck by this example of the Queen’s English in her Christmas message containing a form of words that would have been incorrect if spoken by anyone else:

"This past year has been one of great celebration for many. The enthusiasm which greeted the Diamond Jubilee was, of course, especially memorable for me and my family. It was humbling that so many chose to mark the anniversary of a duty which passed to me 60 years ago.”

Queen’s Christmas Message

Anyone identifying the expression in question gets a bonus point!

Merry Christmas everyone and a Happy New Year!
