The dodgy factor comes into play, however, if a government ignores one of the most pressing issues for years, publishes obviously false figures and replaces people in the relevant positions who do not agree to lie about the real inflation...
In the UK the inflation rate is based on the cost of new cars and computers washing machines etc. If the UK government used the increases in cost of energy, food and rent the inflation rate would be much higher than its current %. Rather like the UK government saying that everythings brilliant again in the economy because GDP and house prices are rising without considering that overall incomes for most are not keeping up.
