Von Beust announced he wants talks with SPD and GAL, "so that the Left and the Communists have no influence" (heh). Green leader Christa Goetsch has not ruled out taking up the offer -- but would I be in her place, I would be rather unforthcoming at first, this would be dangerous for the party.
What's interesting is that his SPD predecessor, Voscherau, wants first talks between CDU and Greens, instead of his party. *Lunatic*, n. One whose delusions are out of fashion.
