Foulkes, who is awaiting written replies from ministers, said there has been less scrutiny and debate in parliament about the cost of the royals since the civil list was replaced in 2012 by the sovereign grant, which is automatically benchmarked to the equivalent of 12% of the profits of the crown estate, an independent business that hands all its profits to the Treasury.
Foulkes, 83, has argued that there should be changes to the rules to allow parliament to go beyond the current limit of questions, mainly about the cost to the taxpayer of royal residences and events attended by the royals, particularly in the light of continuing concerns over the conduct of Andrew.
He has also tabled a question asking the government to publish annual figures for the cost of royal security and plans further questions about the use of taxpayers’ money by the royal family.
The government is to face questions about Prince Andrew and other members of the royal family’s use of public money after talks to overcome restrictions on scrutinising the monarchy in parliament.
Foulkes has asked ministers to publish details of any briefings provided to the Duke of York by the Ministry of Defence after he left the Royal Navy and during his tenure as the UK’s special representative for international trade and investment from 2001 until 2011.
