Berlin – Before the start of the possibly decisive exploratory round of the Union and SPD in Germany, negotiators on both sides spoke of a good climate of conversation. “It will be very demanding today,” emphasized CSU state group leader Alexander Dobrindt on Saturday before the start of the next round of talks between the CDU, CSU and SPD in Berlin. “The more you approach the last meters, the more difficult (but) the tasks that are to be solved.”
