Veep’s” creator Armando Iannucci is leaving his show after four seasons, Variety has confirmed.

Keeping it in the HBO family, David Mandel of “Curb Your Enthusiasm” will step in as showrunner, first reported by 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,” HBO said in a statement.

Of Iannucci’s replacement, the pay cabler commented, “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” has not yet been renewed for a fifth season, but the pickup seems inevitable given the critical praise and accolades the Julia Louis-Dreyfus starrer has garnered.

Season 4 premieres this Sunday, April 12.
