The professor posted "I have shown that to be lying bollocks to use Steve's expression" at 09.01am on the 15th.

Which part of this can you not comprehend, is it really that difficult for you.

Steve has not used that expression, the professor was incorrect to attribute the expression to him.

For 2 days he has lied, prevaricated, twisted, squirmed and lied some more when the simple solution would have been to withraw the comment.

However the professor can NEVER admit that he has made an error can he.
