Newcastle United managing director Derek Llambias has resigned from his role at the club.
Llambias began his role in 2008, but just a day after Joe Kinnear returned to the club as director of football, he has made the decision to leave St James' Park.
In a 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."
Llambias is a long-term friend of owner Mike Ashley.
