Bernie Ecclestone has confirmed he has spoken with Munich prosecutors about the Gerhard Gribkowsky corruption affair.
F1's chief executive acknowledged there has been suspicion about his involvement in the mysterious $50 million payment made to the jailed German banker amid the sale of the commercial rights to CVC some years ago.
The Suddeutsche Zeitung newspaper said Ecclestone was questioned in Munich earlier this month.
"I have been cooperating with the investigation of the affairs of Dr Gribkowsky since the outset," the 80-year-old confirmed in a statement to the media.
"I am confident that when the full facts have been established, I will be exonerated of blame for any wrongdoing," added Ecclestone.
