I'll tell you what I think:
I think that Mr Darling and Mr Brown are a prize pair of pr1cks!
If they think that a 2.5% cut in VAT will get this country spending again they are living in cloud cuckoo land

.
If they had put money directly into the pockets of the consumer it would have been far more beneficial.
I cannot believe (well actually, I can) that he has the audacity to reduce VAT in one sentence and then INCREASE fuel duty so that there is no saving at all on fuel. In fact, he has actually increased the cost of fuel to UK businesses. At the moment, businesses can re-claim the VAT on fuel at 17.5%. As of monday, they can only re-claim 15% of the cost of fuel. Hence he has effectively increased the cost of all goods in the shops as the cost will have to be passed on, offsetting the cut in VAT on everything he has just reduced. What a tool.
Also, can you REALLY see retailers re-pricing all of their goods??? I can just see the bloke who runs the corner shop re-pricing all his Mars Bars by 1p. Not!!
£300 off a Mondeo is not going to make people decide whether to buy one or not.
He has run the risk of the pound be devalued massively and landed UK plc in mountains of debt for little or no reward.
