Tehran - Iranian government rent-a-mob heavies have stormed the British embassy and desecrated the Queen's portrait before setting it alight.
Witnesses have described how bodliy functions were used to make a statement in broad daylight about the Queen Elizabeth II likeness seen hanging in the UK envoy's office.
Students had earlier vandalised the Pietro Annigoni limited edition print with a Hitler mustache and devil horns.
Then someone disguised in a Halloweenish ayatollah costume emptied his bladder all over the painting before smearing dog poo all over its face.
The outrage comes amid reports that President Ahmadinejad has rushed through legislation downgrading the British embassy to the diplomatic equivalent of a junk bond.
Quite why this flare up is taking place is not entirely clear - although last month UK and US spooks in a joint operation unmasked a plot to rub out the Saudi ambassador to Washington, one Shaikh Adel Al Jubeir.
Two Iranians were then blamed for the plot which included the hiring of a Mexican narco-terror hitman to do the evil deed in a Washington DC restaurant.
Iran has denied all allegations, of course, and blamed Mossad in a customary finger-point exercise.
Today's Tehran mayhem may be the first of many nasty incidents to put pressure on legation staff to up sticks and scarper.
Foreign Secretary William Hague's blood pressure is said to be going through the roof.
