As well, The Independent has an article on the Queen's request for a raise. Here's her current situation:
The queen's wealth can be divided into the income she receives from the Government and earnings from her estates and investments. The public cost is partly funded by the Civil List, while further taxpayers' money is spent on the upkeep of the occupied palaces and the Royal Family's travel on state business. Prince Philip receives a grant of £359,000 for his state role as consort to the Queen.
The Queen continues to generate income through the privately owned 46,000-acre estates of the Duchy of Lancaster. This year it rose from more than £11.7m to £12.6m. This helps pay for her private estates and some expenses for the junior royals.
