Under Germany's constitution, Merz needs a two-thirds majority to get the changes passed. With the support of the Greens and Social Democrats, he should succeed. Urgent motions by both the AfD and the Left to challenge next week's sessions of the outgoing parliament failed at the constitutional court on Friday, enabling the vote to go ahead.

Germany’s chancellor-in-waiting Friedrich Merz reached an agreement with the Greens party on a fiscal reform package for large investments on infrastructure and defense, according to a report by newspaper Handelsblatt.
