I note the TUC's reaction to the CBI's tax report. The Guardian reports Brendan Barber as saying:
The chancellor must use his budget to give a firm no to this special pleading and strongly rebuff the business lobbying for a U-turn on the inadequate proposals to levy non-doms.
The CBI's call for a big reduction in corporation tax would increase opportunities for big businesses and the super-rich to avoid paying their fair share of tax.
It would lead to tax hikes for ordinary people, damaging cuts to public services and abandoning commitments on child poverty.
The CBI might as well hang a giant 'tax is for the little people' banner from their office windows.
I'd go with that.
