I have commented on this guys use of public funds before so I have to give him his due. In this article (http://www.bbc.co.uk/news/uk-england-northamptonshire-22583855) he has declared that he will not be claiming for using his own car on official business. Good for him.
OK; now the cynical side of me comes out: The estimated saving is £3,000. I wonder how much his total expense claim will be for the year on top of his £70,000 salary.
