As a first step towards the World Cup teams, please find below the six Six Nations squads as originally published. Inevitably there will be additions and subtractions along the way.
Their summer programmes differ widely: the dates of training sessions and warm-up matches adding to the unpredictability of future events. Even the number of players called up varies by as much as thirteen.
It will be intriguing to see who make it through the coming hurdles, in particular the many uncapped players.
