"Veep" creator Armando Iannucci has stepped down from his position as showrunner after four seasons. HBO announced the decision on Friday, April 10, revealing that "Curb Your Enthusiasm" executive producer David Mandel was appointed to take over the job.

"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," the network said in a statement. "Armando is not replaceable but we are confident that 'Veep' will continue to be produced at the highest levels with new showrunner, David Mandel. David has worked with HBO for many years as executive producer, writer and director for 'Curb Your Enthusiasm'."

"Veep" will debut its fourth season this Sunday, April 12 at 10:30 P.M.

Armando Iannucci recently talked about Selina Meyer's (Julia Louis-Dreyfus) big transition from a Vice President to a POTUS, and how it would affect the show's writing. "This season it was about preserving the basic DNA of the show," he told The Hollywood Reporter.

Of how the new position changed Selina, he said, "There's a lot more pressure on her and we felt that her status has changed. People are going to behave differently to her even though they know her really well. They're going to have to curtail how they talk to her. They can't talk to her the way they used to talk to her unless she gives them permission. But other people, they're going to be a bit nervous, or a bit excited in her presence, so that's important. Some of her opponents are going to have to be a little bit more diplomatic with her."

Iannucci continued, "As we enter the season, she relishes the new power... I wouldn't say she's corrupted by it. She's not a corrupt person. She has a set of moral principles she wants to adhere to, a set of beliefs. But what you'll see is her working out what the limitations are of that power, the frustrations."
