A Royal Badge for Wales was approved in May 2008. It is based on the arms borne by the thirteenth-century Welsh prince Llywelyn the Great ("blazoned quarterly Or and gules, four lions passant guardant counterchanged"), with the addition of St Edward's Crown atop a continuous scroll which, together with a wreath consisting of the plant emblems of the four countries of the United Kingdom, surrounds the shield. The motto which appears on the scroll, ("I am true to my country"), is taken from the National Anthem of Wales and is also found on the Welsh designs for £1 coins minted from 1985 until 2000. The badge formerly appeared on the covers of Assembly Measures; since the 2011 referendum, it now appears on the cover of Acts passed by the Senedd and its escutcheon, ribbon and motto are depicted on the Welsh Seal.
