Deutsche Bank co-chief executive Juergen Fitschen went on trial on Tuesday accused of giving misleading evidence in connection with the collapse of the Kirch media empire in a case that could prove a major distraction for a bank pursuing a strategic revamp. In one of the highest-profile corporate trials in Germany, Fitschen has vowed to fight allegations he gave misleading testimony in a civil suit brought by heirs of the late media magnate Leo Kirch.
