Once we leave the EU the position of Kolpak players becomes very uncertain. Currently they don't need work permits as they are allowed 'freedom of movement' as if they were European citizens (because of their country's trading relationship with the EU) and can play rugby here without needing a work permit or being classified as an 'overseas' player'. Once we leave the EU, and potentially freedom of movement ends, then the automatic right of Kolpak players to ply their trade here will go. They will then, I think, need work permits and would then be classified as 'overseas' players by the Premiership/RFU which under current regulations would limit how many could play for each Premiership team. Whether exceptions can be negotiated for players who are 'Kolpak' at the point of the UK's departure from the EU is possible I guess-and may account for our enthusiasm to sign some SA players at the moment.
