Yes it does. As Lydia says, BIS, RBIS and Best Puppy in Show.
If you get the dog papers the qualification for Crufts 2007 was printed in it either last week or the week before. (sorry, i get both so can't remember which one it was) and it does state the above for qualifying. I wasn't sure til last year when I got RBIS and someone told me that would qualify him. He was already qualified beforehand but it was interesting to know.
If your friend wants absolute clarity just get them to call the kennel club to confirm, but it is true.
