Thank you all for your help. Thank goodness the webmaster contacted me himself and seems to be a nice fellow (I have seen bigger AHs) and removed the duplicate content instantly.
Thank you Ladbrokes for not condoning content theft and offer full investigation.
For whatever reason that affiliate had the duplicate text online I am sure he has learnt his lesson but we can all find in a similar situation as copyscape is not bulletproof to be sure it is unique content. Being patient and notifying the affiliate programs works for me in 99% of all cases :wink-wink
Solved I hope.
