From Slovenia, PM-to-be Borut Pahor, who promised a 50/50 cabinet after the election victory, signed too.
From France, I see Delanoë scooped both Royal and Aubry - but not Buffet.
From Germany, re recent discussion with Martin, Kohl's former pitbull, Heiner Geißler of the CDU among the signatories. Federal minister for Family, Senior Citizens, Women and Youth, and Merkel confidante, Ursula von der Leyen shows her colours too.
I see some countries still have to hear from it, like the Czech Republic - for which Vladimír pidla signed it! (Not bothering about the accents like I do, BTW.)
The largest number of signatories seem to come from Turkey. *Lunatic*, n. One whose delusions are out of fashion.
