BERLIN (AP) — German parties' newly elected parliamentary groups are holding their first meetings after an election that left Chancellor Angela Merkel's conservative bloc weakened but still on top. It now faces a complicated task of forming a coalition government and the prospect of robust opposition from both the right and left.

The most politically plausible option for the next government led by Merkel is a three-way coalition with the pro-business Free Democrats and the traditionally left-leaning Greens.

Merkel has said she wants to seek talks with them, but also with her former coalition partner, the Social Democrats — who say they will go into opposition.

Lawmakers for the nationalist, anti-migrant Alternative for Germany, or AfD, who have entered parliament for the first time, will also meet Tuesday in Berlin.
