The ITV drama will see the pair play lobbyist and GP Guy and Mona Harcourt, whose lives are thrown into turmoil when the doctor's brother is murdered while he is working overseas for a medical drama.

A synopsis from the broadcaster said: "As the death brings buried secrets to light, Mona's family finds itself under suspicion, each drawn deep into a tangle of betrayal and conspiracy as they try to protect their loved ones and careers.

"Mona finds herself facing the ultimate dilemma: how far would you go to keep your family safe?"

'Indian Summers' writer Paul Rutman has penned the script for the show, while 'Mandela: Long Walk To Freedom' filmmaker Justin Chadwick will direct the series after being drawn in by the "gripping and intelligent" script.

And Justin can't wait to work with Jack and Archie.

He said: "I was instantly hooked by Paul and Natasha's gripping and intelligent script. This is a highly relevant and important story in today's multicultural Britain, telling - from a domestic perspective - how a family can be ripped apart by events larger than themselves.

"I'm excited to be working with such stellar talent in Archie Panjabi and Jack Davenport, who are perfectly cast as a loving couple struggling with divided loyalties."

Filming on 'Next of Kin' - which is being made by 'Poldark' and 'Victoria' producers Mammoth Screen - is scheduled to begin next month.

No air date has been set yet, but the six-part thriller is expected to hit TV screens either at the end of this year or early in 2018.
