Taxing matters.

Little worried by this proposal to combine income tax and national insurance which would see national insurance payments abolished but the basic rate of income tax rise from the current 20% to 32%.  As a pensioner, I do not pay national insurance, so where would that leave me?  Perhaps all will be made clear - or indeed maybe the idea will come to nothing - but I, and I imagine many others, would have real difficulty dealing with a 12% rise in income tax.
