By Kirsti Knolle and Madeline Chambers BERLIN (Reuters) -German conservatives under Friedrich Merz vowed on Monday to quickly form a government after winning a national election but face tricky coalition talks and the prospect of an obstructive parliament after far-right and far-left parties surged.

Merz expressed concern over changing relations with Washington under the Trump administration, emphasizing the need for gradual independence from the U.S.

The Christian Democrats won with 28.6% of the vote while the far-right Alternative for Germany came second with 20.8%.
