The 105-member Convention on the Future of Europe decided at its final session on Thursday to add a reference to the symbols of the 15-nation bloc, due to be enlarged to 25 states next May, in a draft constitution submitted to EU leaders.
The official EU anthem is the "Ode to Joy" from Beethoven's Ninth Symphony, the flag is the dark blue banner with 12 yellow stars in a circle, and the motto is "United in Diversity", not dissimilar from the first motto of the United States, "e pluribus unum".
