The Greens and the FDP also agreed to hold consultations before negotiating with the Merkel's Union.

Meanwhile, the head of the Bavarian Social-Christian Party in the Bundestag, the lower house of the German parliament, Alexander Dobrinth, criticized the talks between the small parties, commenting that they would only be reliable if all possible members of a coalition participated in it.

Within the conservative parties, an internal struggle takes place, after the electoral failure on September 24.

Meanwhile the Bavarian CSU demands a higher right-wing profile of the Union, insisting on an upper limit of refugees in Germany and a more rightist profile of its conservative alliance with the CDU.

The CDU and the CSU will meet on October 8 in Berlin to discuss a common line before holding exploratory talks with the Greens and the Liberal Party.

At the same time, the Social Democratic Party of Germany and the Left Party also criticized the development of talks between the parties of a possible future government coalition.

'If these chaotic talks give us an idea of the work of a future government, Germany will enter an era of turmoil,' said Bundestag General Secretary Carsten Schneider.

Socialist party Chairman Dietmar Bartsch reproached the Liberals for 'haggling over the price of their participation in the government,' while 'the Greens are avid for power.'
