Competing teams from France, Ireland, Italy, Wales, and Scotland, were divided into four pools of four, in which teams played home and away matches against each other. Cardiff and Swansea did not compete due to a dispute with their union, the Welsh Rugby Union, whereas teams from England did not compete due to a dispute between European Rugby and the Rugby Football Union. The pool winners and runners-up qualified for the knock-out stages.
