VAT on Food?

I heard a discussion on the radio (LBC 97.3) on Sunday. There is a rumour that the Government might add VAT to food.

The UK currently has massive debts from the recession and bailing out the banks. Taxes apparently need to be raised somehow, and VAT is one of many taxes.

The majority of food is currently tax free - only luxury foods are subject to VAT.
Rumour is that VAT could be applied to food at a lower rate, maybe 3% to 5%.

I guess it's just another bloody good reason to grow my own. The more I learn now, the more I'll grow, the better I'll grow it, the more I'll save .....
