Mr Stevenson.

Mr Smith reads the latest example of political rhetoric failing to match up to political delivery on environmental matters.

"... The Climate Change and Transport Minister, who claimed he would try to ditch his ministerial car to help the environment, has been caught burning rubber. Stewart Stevenson came to power last year pledging to only use his chauffeur-driven limousine when it was strictly necessary. While in Edinburgh, he added, he would try to walk between meetings in order to reduce his carbon footprint to a minimum.But published records show that Stevenson's taxpayer-funded limousine has been busy at work. The minister made 165 trips in the car in his first five months in office, using Volvo S80s or Honda Civic hybrids just as much as his predecessor in the job ..."

Well he is a millionaire, don't you know .... and used to spend his time driving Alex Salmond around before he became First Minister. Old habits are hard to break.
