When you see rottenness in a system you must ask: does it come from one bad apple or does the whole barrel stink?
The rank smell emanating from the coalition is impossible to miss. At first sniff, it appears to come from the blazered figure of Iain Duncan Smith. It has taken me some time to identify its source, because appearances deceive. From his clipped hair to his polished shoes, Duncan Smith seems to be a man who has retained the values of the officer corps of the Scots Guards he once served.
