Well it had to happen sooner or later - HRH has had enough and Ryan Parry's happy snaps from inside the Palace have proved too much for the Royal Household.
Reports suggest that an injunction is being sought to prevent the Mirror from publishing any further pictures or details about life inside the Palace. Proceedings are also said to be underway for Breach of Confidence.
The real concern for the Royals should be the shoddy security that allowed this to happen. That poses more of a threat than the pictures published by the Mirror.
So the gloves are off and while the palace examines its legal arguments to support a breach of confidence action, back at the Mirror, Piers and Ryan will no doubt be preparing a robust defence of public interest.
Media Beak examines the facts:
1. Previous Breaches of Confidence at the Palace
Burrell writes his book
Mirror serialises parts of book
George Smith makes numerous allegations
Mark Bolland discloses conversation with Sir Michael Peat about Prince Charles' sexuality
Common theme - Palace did nothing about them
2: Outrage at slack security after Aaron Barschak gatecrashes Wills 21st party
3: Complaints about £millions spent on policing Bush's visit
4: Parry and Mirror expose outrageous lack of security at Palace.
The case for the Palace
Employees sign a confidenctiality agreement and Parry has breached this and falsified facts to gain employment.
Mirror is further breaching confidence by publicising details and pictures from inside the Palace.
The case for the Mirror and Mr Parry
Confidentiality agreement is not worth the paper it is written on as has been shown by far more serious disclosures in respect of Burrell and others.
If confidentiality has been breached then it is not just in the Royal Household's interests (to show them how bad their security is) but in the public interest on two levels - first, our Monarch is not properly protected and second, why is the txpayer paying £millions to police Bush's visit when it is that easy to get into the Palace.
Mr Parry and the Mirror were exposing how easy it was to get into the Palace and how pathetic the security is. They have not been spreading untrue rumours or sordid details but merely showing how easy it was to get in and argualby, the photographs provide some documentary proof of this.
Media Beak concludes that Palace lawyers are going to have a right royal battle on their hands to exercise their selective right of action for breach of confidence in this case.
The public interest case would seem to be compelling.
Syndicating the Palace snaps for profit might not entirely assist the Mirror's public interest defence but if litigation does ensue then the courts are going to have to make a much more convincing case than the Palace would appear to have in seeking to censure the press on this one.
