Comedy writer Armando Iannucci has been struggling with the demands of the show while his wife and three children remain in the U.K.

A representative for HBO, the cable network behind the show, tells The Hollywood Reporter, "We have had conversations with Armando for some time about the challenges of maintaining his family life in London and producing a show in the States."

David Mandel, who worked with Louis-Dreyfus on Seinfeld, has been brought in as Iannucci's replacement.
