Derek Llambias has resigned from his post as managing director at Newcastle, the club announced this morning.
Llambias' resignation comes a day after Joe Kinnear was confirmed as the club's director of football on a three-year deal.
In a short statement on the club's official website, Llambias said: "I have had an incredible journey during my five years at the club, including some challenging times. I will reflect with great fondness on my time in the north east and, in me, Newcastle United have a lifelong supporter.
"I want to thank the staff for their hard work, our fans for their support of the club, and wish them all well for the future."
