"Throughout recent years of considerable change and expansion for the group, the core Sports Fascias' proposition has continued to be developed and enhanced. "I am delighted that the most recent six weeks' trading has continued to give confidence for the future. I also expect considerable further progress elsewhere in the group in 2014."RD
