'Angela Merkel's fall has begun' amid coalition crunch talks
Politicians in Mrs Merkel’s Christian Democratic Unionists (CDU) are also said to be growing dissatisfied with her leadership, according to Swiss website Aargauer Zeitung.
The claims have come as the Chancellor seeks to form a coalition with the centre-left Social Democrats (SPD), after elections in Germany last year failed to secure the CDU a majority.
The two parties have agreed compromises on care and pensions laws, but the emotionally-charged topic of reuniting temporarily sheltered refugees is said to be off the table.
Coalition talks could end on Sunday night, with little desire for a government alliance between Merkel’s CDU and the SPD.
