Budget. Especially after Covid, the nations were struggling individually to finance their rugby 7s programme, whereas Team GB has lottery funding, so it made more sense from a money standpoint to combine them. Theoretically, this should have made an all-star team as they had the best athletes from all 3 nations to pick from. so this would allow them to train together ahead of Olympiad events, where they've traditionally participated as GB.

@@GetStronk not the point why are THESE COUNTRIES ALLOWED TO COMBINE as GB WHEN EVERYONE ELSE REPRESENT THEMSELVES At the Olympic

@@richardmatatahi4563 Because the UK is recognized by the UN and as such, is the only National Olympic Committee in that region. The individual countries don't have NOCs, and you need an NOC in order to be invited to the Olympics.

@@GetStronk Many recognize themselves as being English not welsh scottish or Irish So because they are the only NOC in that region they can bend the Rules and combine and all other countries are invited to compete at the Olympic's by the NOC and ain't members countries? Yet they compete as individual countries at the Commonwealth Games. Really sounds like you can make the Rules up as you go along up there.
