Angela Merkel faces a showdown with a rebellious minister today that could bring down her government and lead to the end of her political career.
In an open challenge to the German Chancellor, Horst Seehofer, the Interior Minister and leader of her Bavarian sister party, is threatening to order police to start turning away migrants at the border today, after an ultimatum he issued last week expires.
Such a move would leave Merkel with a choice between sacking him and risking the collapse of her government, or suffering a potentially fatal blow to her authority.
The chancellor was holding crisis meetings with her inner circle amid unconfirmed reports Seehofer and his Christian Social Union party (CSU) are ready to step back from the brink and offer her another two weeks to come up with a European solution.
"No one in the CSU is interested in overthrowing the Chancellor or bringing down the government," Seehofer told Bild am Sonntag.
