I don't quite understand what's your point.
Austria, Belgium, Bulgaria, Croatia, France, Germany, Italy, Malta, Netherlands, Poland, Slovakia, and Slovenia - 12 EU member countries are represented by theirs heads of state. Additionally, two more are represented by the heirs apparent to their thrones and one is represented by its Prime Minister. The other EU members are represented by less ranking officials, some of them being mere ambassadors, but mostly ministers of government.
I;ve just noticed that Israel is represented by its Minister of Culture. Shocking.
