The producers of "Downton Abbey" say the upcoming sixth season of this popular drama will be its last.

Executive producer Gareth Neame said its creators "wanted to close the door of 'Downton Abbey' when it felt right and natural for the storylines to come together," and promised "a final season full of all the usual drama and intrigue."

The Emmy Award-winning show follows the fates of the aristocratic Crawley clan and their servants amid the social upheavals of the 1910s and 1920s.

The fifth season of "Downtown" aired in the United States on PBS this winter.

It first aired in the United States in 2011, becoming part of a global phenomenon.

Stars include Hugh Bonneville, Jim Carter, Michelle Dockery, Elizabeth McGovern and Maggie Smith.
