Resignation of long-time euro skeptic Peter Gauweiler

Matthias Kullas told Handelsblatt Global Edition that he doubts that there will be long-term consequences for Ms. Merkel.

"Gauweiler was very prominent and stood out in front. I don't think that many others are going to have the courage to do the same." In fact, Mr. Kullas argued, many will see what happened to the Bavarian lawmaker and think twice about voting against the government again on Greece. "There is definitely unhappiness in the party about Greece, but I don't believe that anyone wants to take on the political responsibility for forcing Greece out of the euro zone," Mr. Kullas said.
