Is that the royal "presume?"

Somewhat disconcertingly, Buckingham Palace seems somewhat less than certain who Canada’s head of state is.

"I know this comes on the back of what might have been said recently in the press, and obviously we’re not getting involved in anything that was said," said palace press officer Nick Loughran. He then added, a bit hesitantly: "In terms of her official title, I presume the Queen is head of state in Canada."
