Yes and no. The United Kingdom Parliament has authority over Scotlands territory, though Scots don't see themselves as British for the most part.
Anyway, McNish does have three wins in sports cars but I guess that's not quite high enough for that group. My opinion is Moss is the top of that list though his sports car wins aren't as high as others. He was involved in F1 as well though and not strictly sports cars. I met him and his wife last year in Phoenix. A friend asked him if he ever raced a Cobra and he replied "thank God no"! Then he chuckled! An incredible man!
Ickx is probably the best sports car racer of all time but he's from Belgium.
