In September 2006, a proposal for a county flag was introduced, largely on the initiative of BBC Radio Derby. It consists of a white-bordered dark green cross encompassing a golden Tudor rose (a historical symbol of the county) all set in a blue field. The blue field represents the many waters of the county, its rivers and reservoirs, while the cross is green to mark the great areas of countryside. The flag was subsequently registered with the Flag Institute in September 2008.
