I've just found
this article by David Davis in today's FT, which (although he is of course only a humble backbencher) gives some idea of what cuts the Tories are thinking of. (Incidentally, isn't it indicative that an OP about Gordon Brown has naturally segued into a discussion of what the Tories would do in government? Should we get back on topic?).
There's some silliness - "symbolical" attacks on fat cats, which are apparently not cheap politics if it's public sector fat cats - but some bigger ideas. A couple that stand out are:
Pay and recruitment freeze in the public sector: Pay freeze maybe - but I can't imagine people going for a reduction in police, nurses, prision guards etc., which is what a recruitment as opposed to headcount freeze implies.
Cutting the salary for junior doctors: of all the deserving targets, we pick frontline medical staff? Really?
Saving £8-10bn (now we're talking real money) in welfare: The plan is to cut "welfare for the wealthy" while protecting "the worst off". This is all motherhood and apple-pie - who is "worst off", who is losing money, how much are they losing? Given that he's just attacked tax credits for being bureaucratic and inefficient, planning more mean-testing across more benefits seems a little odd.
Fair's fair: cut's do have to be made, and there's at least some detail of what will rather than won't be done. But particularly for critical areas like health and welfare, I'd far rather the knife were being weilded by people who haven't been itching to carve the whole thing up for decades.
