Merkel suffers drubbing in Berlin vote due to migrant angst

Merkel's CDU polled 18 percent, down from 23.3 percent at the last election in 2011, with the centre-left Social Democrats (SPD) remaining the largest party on 23 percent. The SPD may now ditch the CDU from their coalition in the German capital.

The blow to the CDU came two weeks after they suffered heavy losses in the eastern state of Mecklenburg-Vorpommern. The setbacks have raised questions about whether Merkel will stand for a fourth term next year, but her party has few good alternatives so she still looks like the most likely candidate.
