What lies has he actually told?
I can understand why some people might think he did the wrong thing, but he hasn't denied driving from London to Durham or making the round trip to Barnard Castle. I must admit I thought his reason for the latter seemed a bit strange but we don't know that he isn't telling the truth.
We do know however that lies have been told about him, like the guy who made up seeing him in Durham on 19th April.
