BERLIN/FRANKFURT (Reuters) – Commerzbank (CBKG.DE) Chief Executive Martin Blessing will step down from the role next October, the bank said on Sunday, leaving Germany’s second largest lender seeking a new CEO as it comes out of a turnaround. Blessing, who has been CEO since May 2008, will see out his current contract, which runs until the end of October 2016, but did not accept an offer to extend it beyond that, Commerzbank said in a statement. “I deeply regret this decision and was hopeful that we could extend the contract,” Supervisory Board Chairman Klaus-Peter Mueller said.
