The key economic event of the week - in the UK at least - is also likely to be the biggest anti-climax.

Gordon Brown's last Budget, says Capital Economics' Roger Bootle, is likely to be 'one of the most boring Budgets ever - and that is against some pretty stiff competition' (much of it from Mr Brown himself, might we add).

But that doesn't mean he won't find a way to pick your pocket somehow - after all, a Brown Budget just wouldn't be the same without a stealth tax or two, now would it?

The most obvious way to squeeze through yet more tax hikes in Wednesday's Budget is to play the green card. Mr Brown and David Cameron have recently been trying to gain the moral high ground on this topic. The electorate is almost certainly far more concerned about crime and education, as the public generally tends to be, but with global warming the new religion (with The Independent looking more and more like a latter-day version of the Watchtower every day), clearly both Gordon and Dave feel they can't go wrong.

Not that we need more taxes. The shadow chancellor George Osborne, reckons we've seen 99 tax hikes since 1997, and Mr Brown's on for the century on Wednesday. Figures from the OECD have already shown that the tax burden in the UK has already grown from 39.5% of GDP in 1997 to 42.7% this year - one of the biggest increases in the western world, according to The Telegraph.

But which green tax to go for? The latest suggestion is that 4x4s and sports cars will be attacked with higher road tax - having already hiked air passenger duty, which hits less well-off tourists more than the wealthy, he might be tempted to tackle the demon gas-guzzlers to show some semblance of equality. After all, only the well-off drive them and everyone else apparently hates the Chelsea tractor brigade, so it should be an easy grab.

There's also likely to be more 'loophole' closing. We like the way that Mr Brown uses the word 'loophole'; somehow making it seem that perfectly valid ways of making your investments more tax-efficient are in fact sneaky, nigh-on criminal manoeuvres aimed at cheating the State out of its due. We have a sneaking suspicion that he'd like to say: 'We've decided to shut a loophole that allows higher-rate taxpayers to keep a full 60% of their income above the £35,000 mark, by raising the higher-rate tax rate to 100%.'

Then of course, we'll have the crowing about his economic forecasts. He looks on course to meet his public borrowing target of £37bn this year, which he will certainly be pleased about. But in reality, this is nothing to be proud of. As Bootle reminds us, six years ago the Chancellor predicted public borrowing this year would be £12bn. That's a margin of error of more than 200% - even Michael Fish would laugh at that forecasting track record.

And then there are his much-vaunted rules. There's his golden rule, which has been yanked and manipulated so much it should really be called the elasticated rule. Meanwhile, he claims to have kept government spending to below 40% as a proportion of UK GDP, but 'if you add in all the off balance sheet items and public sector pension liabilities you could readily reach a figure as high as 80%,' says Bootle.

But all in all, Mr Brown may well be quite pleased as he leaves the dispatch box on Wednesday. After all, it looks like he's done a Greenspan (the new term for setting up an economic crash then escaping just in time to leave your successor to deal with the mess).

The only problem for Mr Brown, however, is that if things go his way, he'll be sitting right next door while the next chancellor is reaping what his imprudence sowed. Suddenly the prospect of becoming prime minister just doesn't look as inviting.

And in London this morning, plumbing giant Wolseley became the latest casualty of the US housing slump, announcing a 15% fall in first-half profit. Despite cutting 4,000 jobs at its North Carolina-based building materials supplier, Stock, and expanding its European operations in reaction to the softer US market, net income had fallen to £209m compared with £245m the previous year. Having fallen nearly 2% on Friday, however, Wolseley's share price had climbed by as much as 3% in early trading today.
