German FM Gabriel says he won't be part of next government

German Foreign Minister Sigmar Gabriel has tweeted that he will not be a part of the next government.

Gabriel wrote Thursday that the heads of the Social Democratic Party had informed him of the decision and that he is deeply grateful to have worked for his country and the party in leading positions for many years.

The move comes after weeks of turbulence in Gabriel's party after it clinched a coalition deal with Chancellor Angela Merkel's conservatives.

The infighting also included a public falling-out with then-party leader Martin Schulz, who was vying to get the foreign minister job. Schulz has since abandoned that ambition, too.

Gabriel has been one of Germany's most popular politicians since becoming foreign minister about a year ago.

The Social Democrats will govern the country together with Merkel, who is to be re-elected next Wednesday.
