Commerzbank approached the larger Deutsche Bank about a potential merger, a senior Deutsche Bank executive said, an overture that kicked off six weeks of intensive and frantic but ultimately fruitless talks.

It was the first indication of which bank had initiated talks between Germany's top lenders. The executive spoke on condition of anonymity to journalists on a media call.

However, a spokeswoman for Commerzbank denied that version of events. The talks "started jointly and they ended jointly," the spokeswoman said.
