Germany's interior minister has offered to resign over Angela Merkel's EU deal to tackle immigration, reports say.
Horst Seehofer, leader of the CSU, a key party in Mrs Merkel's coalition, has grown increasingly angry at her position on immigration.
Last week he threatened to turn asylum seekers away from Germany's borders unless Mrs Merkel reached an acceptable deal with other EU partners.
His stance put Mrs Merkel's coalition and her political future in question.
Late on Sunday, Mrs Merkel's Christian Democratic Union (CDU) passed a resolution supporting her position on migration. CDU General Secretary Annegret Kramp-Karrenbauer said the party believed a European solution was necessary.
But separate reports from sources within the CDU's Bavarian sister party, the CSU, indicated Mr Seehofer had offered to resign both as leader of the CSU and as interior minister.
