FRANKFURT – The former head of Germany's Deutsche Bank
Politicians have already accused Indian-born Jain, who became co-head of Germany's largest bank in June, of "chickening out" by sending his chief compliance officer in his place.
"I always took these tasks upon myself," Ackermann said at a conference organized by business daily Handelsblatt in Frankfurt. "I think that in this instance, it is the boss who belongs on stage," he added, in a rare public comment on his successor.
The European Commission and other international regulators are investigating more than a dozen banks for alleged manipulation of the London interbank offered rate (LIBOR), which is used to set the price of trillions of dollars worth of financial products worldwide.
The Commission has not identified the banks, but sources familiar with the matter have said Deutsche Bank is cooperating with the EU regulator.
Deutsche Bank said in July initial findings from an internal probe into alleged rigging of global interest rates found that no members of the management board behaved inappropriately.
Any banks found guilty of breaching EU antitrust rules could face fines of up to 10 percent of their global revenues.
Deutsche Bank will send Stephan Leithner, head of personnel and compliance, to the November 28 finance committee hearing.
