BBC - Peston's Picks: Will Osborne cut and simplify corporation tax?‏

"It's true therefore that a policy of reducing the various business tax allowances would have the effect of pushing up the tax burden on the kind of companies that make and export things deemed vital to the UK's economic future, even if the headline rate of tax were reduced - whereas the tax burden on banks would tend to be reduced in these circumstances."

It does seem mad that once again the Tories have pursued a headline when the devil in the detail means they would actually be doing the opposite of what they're claiming they want to do.
But then I don't think they ever said they wanted to improve the lot of manufacturers at the cost of the banks, but I may be wrong
