In his blog Nicky said that he has had the official reason for why he isn't do DOI....but unfortunately he doesn't say what it is!
He sounds as if he is going through a bit of a bad patch at the moment as he also lost a friend to cancer at the age of 42!

Apparently axed because he didnt get on with anyone, and was disliked

Christoper Dean was being very cagey when asked if he got on with him, but by his answer he obviously didnt!
