Sounds like you were gullible to that lie.
Address the inefficiencies and costs on public owned infrastructure, reduce chiefs and increase the Indians. Reduce the amount sent to Scotland, Wales, and Ireland, and have all four on the same per head. Come out of the European court of Rights and do a Trump; round up all the illegals and asylum seekers and ship them out, put the British first (you will hate that).
Sort welfare, needs to be a diminishing system based on what you paid into it. Make relatives liable to care for family members and not local councils. Obviously those that have no family, or family in a similar position will require state help.
Have a PAYG mentality. The more things you use, the more you pay. So for example, scrap VED and put it on fuel. The more you drive, the more fuel you buy, the more tax you pay. Put VED on electric cars. Scrap this climate saving shite. Shake up the NHS. We pay half in tax for healthcare than Americans pay. So PAYG again. You use it for dialysis, you should contribute more because you're using the NHS more than others. So I would rewrite the NHS rules. Miss a doctors appointment, you pay £50, no payment, then no more appointments until you pay it.
I would reduce council tax and local government staff. I would scrap an awful lot of red tape to achieve that. Having to tell your councils how many ducks and chickens you own because of bird flu? Scrap that stupid idea.
Tax the Welsh for wasting oxygen.
