Christian Lindner, leader of Germany's Free Democratic Party (FDP), is under intense scrutiny following the revelation of a controversial document known as the "D-Day" paper.

This document outlined a detailed plan for the FDP's exit from the coalition government, using military metaphors like "open field battle.

" The leak has led to the resignation of FDP General Secretary Bijan Djir-Sarai and Federal Managing Director Carsten Reymann, who were seen as scapegoats to protect Lindner.

During a televised interview with Caren Miosga, Lindner attempted to distance himself from the document, claiming he was unaware of its existence until media inquiries arose.

Despite his efforts to portray himself as a misunderstood defender of fiscal responsibility, Lindner's credibility has been severely damaged.

The incident has sparked widespread criticism and raised questions about the FDP's internal strategies and Lindner's leadership.
