Anne is expected to make a full recovery. No further details have been released. The British "Sun" speculates that it could have been a horse-related accident. Anne is said to have been walking near horses on the estate and may have been hit on the head or legs by a horse. All her appointments for this week have been postponed, the palace announced. She will also be unable to attend the state banquet for the Japanese imperial couple this Tuesday evening. However, it seems the Princess's time off will not be too prolonged.
