Part of the problem is that tax or duty on fuel,alchohol,and tobacco are fixed amounts and not percentages of the price.
The majority of the cost of all three is fixed tax.
Also as the Dollar weakens the cost of Oil,Gold and other safe investments goes up.This means that although there are more Pounds to the Dollar there
are more Dollars for a Barrel of Crude.
If the Oil value remained the same then a Pound would buy you more Oil.It is going up so it doesn't.
