Set in London, Flack focuses on the high-stakes world of celebrity PR. It follows Mills Paulson PR agency as it works to keep their clients most outrageous indiscretions firmly behind closed doors.

Series one saw PR Robyn (Anna Paquin) finally face the consequences of her numerous addictions, as her work and home life collided catastrophically.

With her relationships damaged beyond repair, and even her own sister rejecting her, Robyn realises she needs to make a change.

Paquin will be joined by original cast members, Sophie Okonedo CBE (Chimerica) as PR boss Caroline, Lydia Wilson (About Time) as Eve, Rebecca Benson (Game of Thrones) as Melody and Genevieve Angelson (Good Girls Revolt) as Robyn’s sister Ruth.

Paquin, who also serves as executive producer, said: “One of the most exciting pieces of feedback I received after the season finale of Flack was people begging for more episodes.

“This season I can promise even more of the darkly comedic client dramas, as well as fascinating insight into the tumultuous personal lives of our exceptional ensemble of badass women.”

New additions to the cast include Sam Neill (Peaky Blinders), playing Duncan, who has a complicated relationship with PR agency boss Caroline.

He will be joined by Daniel Dae Kim (Always Be My Maybe), who plays Scott Cole, a tech titan who starts a romance with someone at the agency.

Pete Thornton, UKTV head of scripted, praised Oliver Lansley’s writing and expressed his delight and welcoming back an “extraordinary quartet of female characters”.

The new six-part series will air in 2020 on W.
