I'm not a fan of Paul Burrell, but I believe his version over Spencer's. In addition, Dickie Arbeiter is mentioned in the article with similar claims as Burrell's and of the three I look at Dickie as being quite credible.
I wasn't sure where to put this post..the Spencer thread is pretty long...if anyone wants to move it, my feelings won't be hurt. The article is from 10 days ago.
