The man who oversaw Arsenal's move from Highbury to their new stadium is leaving the club.

Managing director Keith Edelman will serve 12 months notice then move on for a "new challenge".

Mr Edelman said: "I have thoroughly enjoyed my time at Arsenal. It has been a very exciting period for the business and I am proud to have contributed to the club's many off-field achievements over the past eight years.

"I believe it is the right time to seek pastures new and embark upon fresh challenges."

There is no suggestion that Mr Edelman's departure will affect the ownership of the club.

Chairman Peter Hill-Wood said: "Under Keith's stewardship the club has achieved record profits and the Board owes him a debt of gratitude for his contribution. We wish him the very best for the future."
