The duo will head to Ireland in June with their squad following the departure of John Duffy who has been appointed head coach of Kingstone Press Championship 1 side Swinton Lions.
Former Bradford Bulls full-back Graham steps up having been Duffy’s assistant at last year’s championships, and the promotion continues a fine start to 2015 which has already seen him steer his club to win the BARLA Yorkshire Cup ahead of their debut in the Kingstone Press Cider National Conference League in March.
He earned 10 caps for Scotland between 1998 and 2004, and also enjoyed spells with Dewsbury Rams, Batley Bulldogs and York City Knights.
Benn (pictured) – who guided the Raiders to the NCL Division One title last year – played seven times for Scotland between 2006 and 2010.
His playing career included stints at Castleford Tigers, Featherstone Rovers, York City Knights and Dewsbury Rams.
