The far-right Alternative for Germany (AfD) party would win 16 percent of votes if national parliamentary elections were held this Sunday, the party's highest level in a country-wide poll since its creation in 2013, according to a new poll released Friday.

The anti-immigrant party gained two percentage points compared to a similar poll in the beginning of September and would be the third biggest party, overtaking the Greens and the Left, according to the poll by Infratest dimap for TV channel ARD.

Chancellor Angela Merkel's Christian Democrats (CDU) and their Social Democrat (SPD) coalition partners lost a point since the beginning of the month. The CDU would win 32 percent of the votes in a nationwide election and the SPD 22 percent.

Infratest dimap interviewed 1,018 German adults by phone from September 19 to 21.

The AfD overtook Merkel's party in a local election for the first time in the northeastern state of Mecklenburg-Vorpommern earlier this month, and scored 14.2 percent in a Berlin state election Sunday. It now has seats in 10 out of 16 state assemblies in Germany.

An AfD politician elected to Berlin's state assembly said Thursday he would not sit with the party group, but as an independent, after German media reported the group may exclude him. Kay Nerstheimer was a member of the German Defense League, an organization under state surveillance for right-wing extremism and Islamophobia, until 2012 and posted comments on Facebook glorifying Germany's Nazi past and calling refugees "disgusting worms," Süddeutsche Zeitung reported.
