Angela Merkel finally took action to stem the growing panic within her coalition government on Monday when she announced she would step down as leader of her Christian Democrat party (CDU) in December.
CDU leaders will meet next Sunday to prepare for a summit in December where party members will vote for a new chairman.
The SPD leader said she did not want to "leave our fate to our coalition partners" and wait until the government finds a "sensible" working mode. She had won four consecutive terms.

Three months later, her father moved the family to a small-town parish in the communist East at a time when most people were headed the other way. Merkel's one-time mentor, Helmut Kohl, did seek a fifth term in 1998 and lost power after 16 years.
Two prominent candidates immediately threw their hats in the ring for the CDU leadership.
