Becher, who was appointed as CEO in 2011, has already informed the operator’s employees of his decision.

Confirming his departure on networking site LinkedIn, the executive thanked those at Interwetten for “the fun, energy and support” they provided during his tenure.

Becher said: "I informed Interwetten employees today that I will step down as CEO at the end of 2018.

"In seven very successful years, we managed together to more than double turnover to €1.5bn, based on very high profitability. I'm looking forward to ramping up a new challenge in 2019 and I’d like to thank everyone at Interwetten for the fun, energy and support provided on this particular journey."
