It's why the British monarchy had a unicorn on the clay of arms. As at the time Scotland was the only recognised country within the union
(Wales wasn't considered a country at that point). So the coat of arms is made up of 4 quarters 3 lions of England (encompasses Wales). (6 lions total) the lion of Scotland and the harp of Ireland. Flanked by the rampant lion and the unicorn.

I wonder how many sheets of paper are going to be wasted trying to verify this
