According to the article, the lie that the current Danish chair of the rotating Council Presidency is being accused of making by Patrick Breyer is that the European Parliament will refuse to extend the current soon-to-expire voluntary scanning regime unless the EU Council first agrees to implement Chat Control:

“This is a blatant lie designed to manufacture a crisis,” states Dr. Breyer, a long-time digital freedom fighter. “There is no such decision by the European Parliament. There has not even been a discussion on this issue. The Commission has not yet proposed to extend the current legislation, and the European Parliament has not yet appointed Rapporteurs to discuss it. We are witnessing a shameless disinformation campaign to force an unprecedented mass scanning law upon 450 million Europeans. I call on EU governments, and particularly the German government, not to fall for this blatant manipulation. To sacrifice the fundamental right to digital privacy and secure encryption based on a fabrication would be a catastrophic failure of political and moral leadership.”
