A public broadcaster has justified removing the video, saying allegations it had politically manipulated the children were unbearable for editorial staff. However, one news editor called the clip "scandalously good."

German public broadcaster WDR 2 on Saturday issued an apology for showing a video of a children's choir singing a humorous, traditional tune rewritten with satirical lyrics.

The song, titled "My grandma is an old environmental pig," triggered heated reactions on Twitter. One user described the lyrics as "disrespectful," while a WDR news editor said the remake of the traditional tune was "scandalously good."

The lyrics, including verses about grandma riding a motorcycle that burns a thousand liters of gasoline every month and eating a cutlet every day because meat from the discount supermarket is so cheap, include the refrain, "My grandma is an old environmental pig." The video ends with a quote from teenage climate activist Greta Thunberg: "We will not let you get away with this."
