2 July 2007: A Queen, for 60 pence a year

According to the latest accounts released by Buckingham Palace, Queen Elizabeth II costs British taxpayers about 60 pence per person per year.

The head of state's expenditure was 37.3 million pounds, which the palace claims has decreased in real terms by seven percent over the last six years.

5.6 million pounds of this was spent on travel by the queen and other members of the royal family.

The accounts also reveal that the queen's household is becoming greener. It has reduced carbon emissions by 12 percent in the past year, and there are even plans to convert the royal train to run on biodiesel.
