The competition was on a knock-out basis, between eight clubs, matches being played under floodlights on various London football grounds, and the second half of each game being shown live in the London Area only on Associated-Rediffusion's "Cavalcade of Sport" programme, which was aired between 8:30 and 9:30 PM.
The tournament was won by Warrington, who defeated Leigh 43–18 at Loftus Road with Harry Bath, the second row forward, being the hero scoring 22 points from 2 tries and 8 goals.
ITV was launched on 24 September 1955 and the new channel, wanting to make their mark from the start, were quick to add sport to the programmes.
[citation needed] The tournament officially took place in October and November 1955, (the first match actually took place Wednesday 28 September) and the literature stated that the contestants comprised "the top four sides from each county", based on the previous seasons league positions.
However, these rankings do not conform to the finishing positions in either the Championship or the county leagues from the 1954–55 season.
