One of the first things hammered into me as a young PR exec was never to argue with a journalist - they always have the last word. 

Philip Green didn't get that memo.  

This article from the Guardian - back in 2003 - provides a transcript of a series of calls between Philip and a Guardian journalist.  And you do have to feel for the reporter on the receiving end. 

I would not recommend this approach, but he gets away with it.  Most of us wouldn't.
