Surely, the public would not be left in the dark forever about the identity of the person who had tried to make political capital out of this privileged information? Unfortunately, yes.
The issue of MPs’ travel expenses – and its disreputable cousin, government spending – have thrown up a pretty interesting moral distinction. Government spending, which provides services to the general public, is seen to be an intrinsically bad thing that must be rationed.

The worth is assumed, and is beyond challenge.
