An on-line campaign calling for HRH Kate to be artificially inseminated by an unknown donor has been called "disgusting and outrageous" by the Daily Mail and Tory MP's who are in turn campaigning to have the organisers incarcerated in the Tower of London.

A spokesman for the Mother of the Nation campaign who wished to remain anonymous replied to our email giving his on-line name as "Jimmy Jizz" and explained how the campaign arose.

"I was in my bed-sit with my mates, let's call them Woody and Dick, having a few vodkas and Red Bulls, maybe a few spliffs, watching the Diamond Jubilee and lusting after Kate in that red dress. LOL! We began to wonder how long it would be before she's up the duff and arguing amongst ourselves as to who would be the best candidate to do it, when one of us had a brainwave. WTF! Get her inseminated by an anonymous member of the public. That would signify true union between the people and the next-but-one heir to the throne and Kate could call herself the "Mother of the Nation". Good, eh?

"Just think of it, anybody who wanted to give a sample could whack one off into a massive communal vat of jizz…young or old…black, brown, yellow or white…straight or gay...it wouldn't matter and then Wills could take a turkey baster, dip it in the warm spunk and inject it where the sun don't shine. I'm sure his male relatives would all make a donation too. There would have to be independent witnesses of course to make sure that he just didn't slip one inside her himself.

"Naturally all that communal spunk shouldn't be wasted, so it could then be made freely available to any woman who wanted to share in Kate's Mother of the Nation experience. Simples."

"I think I should sign off now, there's a police van outside."

No-one was available last night for comment from Buckingham Palace.
