Unable as I have been unable to secure any sort of answer to this out of my old mate Tom Hamilton (http://letsbesensible.blogspot.com), I am posting it here in search of answers from the blogosphere in general:

What specific policy of the Blair-Brown Government would anyone expect a Cameron Government to reverse, and how important is it?

And what specific policy of a Cameron/Osborne/Gove/Vaizey/Whoever Government would anyone expect, or even hope, to see reversed by a Miliband/Lammy/Balls/Cooper/Whoever Government, and how important is it?
