This is surprising tbh. When they changed the act of succession to remove default male succession, part of that was negotiating changes in succession acts around the Commonwealth. This implies that some or even most of those are unconstitutional? Weird.
Anyways, it would be more surprising if the Commonwealth didn't lose a couple now and if a couple more didn't make plans for when Charles dies, which won't be all that long from now.
I wish Canada was one of those, but all I'm reasonably hoping for is that we drop monarch icons on our cash.
