“South Park,” the cartoon series that has pushed the bounds of taste for a decade, has perhaps produced its most spectacularly offensive episode ever….well, in Britain anyway.

Snitches close to the throne claim that Queenie “ain’t” pleased with the episode that will depict her blowing her brains all over her fancy white gown.

The scene begins with a clearly alarmed Queen receiving a call on her mobile telling her that an evil British plot to conquer America has gone awry.

She then reaches for a handgun, places it in her mouth and shoots herself. She can be seen tumbling from her throne and in the final image her bloody corpse is depicted lying prostrate on the palace floor.

The episode, broadcast last night in the US, also featured presidential contender Hillary Clinton in a parody of “24″, the thriller that takes place over the course of a day and which typically involves a terrorist threat of epic proportions.

In the course of last night’s show – as well as having the Queen commit suicide – a group of Russian mercenariesworking for the British install a nuclear device in Mrs Clinton’s more intimate areas. The plot is foiled.

South Park, about the lives of four schoolboys in a town of the same name in Colorado, has courted controversy since it first aired in 1997, attracting a large cult following in the process.

Its creators Trey Parker and Matt Stone describe themselves as “equal opportunity offenders” and it is certainly the case that a broad spectrum of society has felt its wrath at one stage or another.
