The budget is just a formal statement of how things have been, how things are, and how things are expected to be with a lot of technical stuff about the country balancing it's books and a little topping of headline grabbing popular nonsense like tax cuts and silly financial initiatives to "help" people.
Given that the world economy is in a dire mess, UK's economy is even worse, in order to balance the books there should be deep painful changes to public spending and taxation.
If there is all credit to the chancellor.
I suspect that given that we must have an election in the next year the chancellor will do a political fudge where there will be a few well targetted gimmicky giveaways, bread and butter increases on the usual taxes, a minimal reduction in public services and a minimal set of tax rises (just so they can pretend to have been "responsible") but really just leaving things as they are now for a year to get us out of the worst of the recession and more importantly force the next governement (almost certainly conservative) to be the brutal bully boys who have to really sort out the mess.
Ho Hum business as usual then - Labour wrecks the economy and Tories repair it and we all suffer.
