WESTMINSTER'S value-for-money watchdog has been called upon to investigate the finances of the Crown Estate after the UK Government announced the landowner would provide the annual income for the Queen and members of the Royal Household.

Ian Davidson, the Labour MP for Glasgow South West and Chairman of the Commons Scottish Affairs Committee, said that now the Treasury had announced the change to royal income he would “ask the National Audit Office to bring forward a full report on the Crown Estate’s finances, so we can have a full discussion on how much the royal family should receive from them”.

He added that the inquiry would complement the one the Scottish Affairs Committee was currently undertaking on the Crown Estate in Scotland.

In the Commons, the Chancellor announced the biggest reform to royal finances for almost 40 years, replacing the Civil List with a so-called “sovereign grant”, equivalent to 15% of the profits from the £6.7 billion Crown Estate.

It is estimated this will be worth around £34 million to the Queen and other members of the Royal Family in 2013/14. A review would take place every seven years.

George Osborne argued that the change would improve flexibility and accountability.

He said Crown Estate profits would increase significantly in the years ahead through offshore wind projects.
