As another poster has said on another thread - is it possible that the Len/Craig tiff was staged to divert things away from the John leaving scenario?
Also I have noticed that Craig just seems to laugh at Len nowadays and patiently puts his point across.

What made me laugh was when Len said to Craig that he always says negative stuff and never positive - which is absolute balls and a bit hypocritcal after they way ALL the judges made negative comments over John!!!
