German voters cast their ballots in Sunday’s election, with opposition leader Friedrich Merz claiming victory and Chancellor Olaf Scholz conceding defeat. Alternative for Germany, or AfD, is heading for the strongest showing for a far-right party since World War II.

The leader of the far-right Alternative for Germany (AfD), the second largest party in parliament after Sunday's election, said Germany's likely next chancellor would be held hostage by left-wing parties that would seek to loosen tough fiscal rules.

"The members have the final say," said party chairman Lars Klingbeil. "The members will make the final decision." Klingbeil is expected to take on leadership of the SPD's much reduced parliamentary group on Wednesday before representing the party in coalition talks with the CDU.
