According to this report in the Times of Israel, Michael Sommer, head of the DGB — Germany’s national trade union centre — was the guest of honour at the Arno Lustiger Award at the third annual German-Israel Congress on Sunday in Berlin.

Sommer came down forcefully against those advocating a boycott of goods from the Jewish state.

“As long as I am head of this organization,” he said, “there will never be a resolution that says ‘Don’t buy from Jews.'”

Sommer’s speech coincided with the 75th anniversary of Kristallnacht, an anti-Jewish pogrom in 1938 that is seen by many as the beginning of the Holocaust.
