Idle, 72, is disturbed by fans love of shows such as the period drama and slammed the show and it's ilk for it's portrayal of "upper class twits" and "sexually available domestic servants".

"I love and adore the English. Well, not all of them. I hate the smugly sentimental upstairs/downstairs world of the upper-classes and their nostalgia for country estates and servants," he told British newspaper The Daily Mail.

"You know, those TV series about fat-faced, smug, f**king upper-class twits where happy and kindly aristocrats are lovingly and gratifyingly served by contented, sexually available domestic servants."

The award-winning writer and actor reportedly clarified to The Daily Mail he was specifically referring to Downton, and further added: "It's c**p. It's condescending and inaccurate, and panders to the worst kind of Americans who see the British as some kind of butler-owning democracy."

The comedic actor, who wrote and sang Always Look On The Bright Side Of Life from cult film The Life Of Brian, based a large part of his career ridiculing outdated ideas of the British class system – demonstrated in Python sketches like The Upper Class Twit of the Year.

Downton Abbey was British TV's most successful export in recent years. The acclaimed period drama, came to an end in the U.K. after six seasons in December (15), while American viewers mourned its passing in early March (16).

Starring Dame Maggie Smith and Hugh Bonneville, it was created by Gosford Park writer Julian Fellowes. The show picked up numerous awards during its run, including 12 Primetime Emmys, and three Golden Globes.
