Campaigners have today called on parliament to change its rules, to allow MPs to raise questions about royals without any restrictions.

Current rules place limits on the questions MPs can ask about members of the royal family, making scrutiny and accountability almost impossible.

The call comes after revelations about Andrew's relationship with an alleged Chinese spy.

Speaking for Republic Graham Smith said today:

"It is intolerable that MPs do not have complete freedom to debate individual members of the royal family. Our parliament must be free to debate anything, without fear or favour."

"The royals are suppose to set high standards of behaviour, yet they stand accused of corruption, secrecy and relationships with numerous people of questionable character."

"Andrew is only the most obvious target for parliamentary scrutiny. But Charles and William have questions to answer about their questionable choice of friends, their secrecy and their abuse of public money."

"It is appalling that MPs are not free to debate the royals whenever they choose to do so, but are told there are questions they cannot ask, issues they cannot raise."

"The monarchy is protected by official secrecy and deference. That has to end, and our elected representatives must be free to challenge the corruption the royals hide in plain sight."
