Seehofer's intervention came after Merkel announced on Sunday that she would lead the CDU into elections next year, seeking a fourth term as chancellor.
Zēhofera paziņojums seko pēc tam, kad Merkele svētdien atklāja, ka ir gatava 2017.gada parlamenta vēlēšanās kandidēt uz ceturto termiņu kanclera amatā.
