Hit series Downton Abbey has entered the Guinness World Records for being the most critically acclaimed telly show.

The Upstairs/Downstairs style show created by Oscar-winning writer Julian Fellowes (pictured) scored a stonking 92 out of 100 on review aggregator Metacritic.

This means reviewers from around the globe rated it more highly than any other TV show in 2010.

Other shows to have won the honour include Mad Men and Modern Family but Downton Abbey is the first Brit show to do so.

On accepting the award,  Downton Abbey executive producer Gareth Neame said: “It is significant that this is the first time a British TV show has been so highly received around the world, confirming the UK’s status as the home of world-class drama.”

The WWI set drama starring Maggie Smith, Hugh Bonneville and Elizabeth McGovern returns to the small screen on Sunday for its second series.
