UKIP won't win a general Election, but hopefully will force the other two parties to listen to the public. I would want the NHS to be paid for by taxation rather than private though as lots of people would struggle. Maybe add to the money raised for the NHS by two things in particular - Food and Smoking, in fact why not include risk activities like sports?
I was a local footballer and have had to use the NHS for desperate injuries, Maybe Sports Insurance should be compulsory, for risky outdoor pursuits like Mountain Climbing etc.
Regarding tax on food-the idea of a junk food levy I like the idea of,plus when I have been on the beer and had a dodgy keebab i would not even know if you charged me more
So keep it funded by taxpayers, but add additional funds by raising extra cash through the above.
