House of Lords - (Reuterus): A giant rat fifty thousand times more corrupt than Robert Maxwell, Sir Oswald Mosely, Anthony Blunt and Lord Haw-Haw put together has been discovered underneath the cover of aristocratic ermine in the House of Lords.
Masquarading for over 40 years as Lord Carrington, the newly-confirmed alien species is in fact a doppleganger lookalike brother of ex-UK Prime Monster Margaret Thatcher.
The Hellfire Club giant rat is one of two British species of convicted molestor, fraudster and embezzlement specialists who has hidden behind the bi-partisan humbug that forged the Blair Administration's 1998 Good Friday Agreement.
And according to the UK Anti-Terror Agency, he may be the ultimate Mossad/KGB double-agent mastermind that allowed NATO military intelligence to overlook the 30 year criminal history of George W Bush.
"We all thought this kind of treachorous bastard to be extinct," an Anti-Terror Agency source said today, "but he's the biggest and ugliest specimen we have ever had the misfortune to come across."
Conservative sources at MI5 also found the giant rat's accomplice - dubbed the Pygmy Possum - and identified the little stinker as Cherie Blair's US PR Guru Martha Greene.
"We think she's the giant rat's love-child," a police source added.
Both species are currently being studied to establish their connection with the latest £1,000 billion bailing-out of the troubled Northern Crock Bank.
An update is expected later in the week on this fast-breaking story.
