JJB Sports announced that Sir David Jones has retired from the board of the U.K.-based sports retailer with immediate effect due to ill health.

Jones first joined the JJB Sports board as a non-executive director in 2007, before becoming deputy chairman in 2008, then executive chairman at the start of 2009. He then stepped back to a non-executive role in January this year, following the appointment of Keith Jones as chief executive.

JJB said in a statement: “Sir David played a crucial role as executive chairman during 2009 at a time when the company was close to administration, leading the company through a succession of transactions and initiatives to secure its survival and to create a platform for growth. The board places on record its enormous thanks to Sir David for everything he has achieved with the company.”
