I can think of two examples offhand: the Paul Burrell case where the Queen stepped in to avoid anyone from the Royal Family having to appear in the witness box. The other example more recently was the Queen intervening in the Scottish referendum by telling people outside church to "be careful what you wish for".
I applaud Mike's attempts at being a thorn in the Establishment's side because there's nothing more they want than an easy ride when they travel back to their second homes full of servants at the weekend.
Burrell was cleared because the Queen herself cleared him:
"The trial of Mr Burrell, who was accused of stealing items belonging to Diana, Princess of Wales, collapsed on Friday after the Queen's disclosure of a conversation with Mr Burrell in which the former butler told her that
he had taken items from Diana's home for safekeeping."
Far from him stealing items and hoping no one would notice the Queen said he admitted to her he took them and told her he did so to protect the property. That negates the notion he intended to steal the property.
Are you suggesting she lied to protect him?
