Wing Commander Nick Mawston was the Chairman of Royal Air Force Rugby League for three years until his untimely death at the age of 43. A driving force in the development of Rugby League within both the RAF and the Combined Services, his passing left a tremendous void. To honour his memory, a trophy was commissioned by the Combined Services Rugby League in 2005, to be contested between the Army and the Royal Air Force every year as part of the Inter-Service Championship.
