Betfred has been announced as the new title sponsor of the Championship and League 1 until the end of the 2019 season.
The bookmaker is already the current title sponsor of Super League.
The Betfred brand will feature on perimeter advertising at all Championship and League 1 grounds, and will also have a heavy presence at the 2018 Summer Bash in Blackpool.
Interim Rugby Football League chief executive, Ralph Rimmer, said: “We are delighted that Betfred have extended their involvement in the sport to the Championship and League 1.
“Betfred’s first year involved in the Super League was an unquestionable success and I am certain that they will bring the passion and enthusiasm to their extended sponsorship.
“The Championship and League 1 provide great entertainment and are an integral part of the game and the fact that Betfred have extended their sponsorship to these tiers of the sport demonstrates the value they see in being involved in Rugby League.
“The Betfred Championship is now one of the most geographically diverse competitions in the world including teams from Toronto, Toulouse and London and with this new deal I am certain both competitions will go from strength to strength.”
Betfred’s Fred Done added: “Our first year as title sponsors of Super League was both a very successful and satisfying one for me and I had no hesitation in agreeing to extend our sponsorship to the Championship and League 1.”
