Bridgerton star joins Bradley Walsh in The Larkins, ITV's adaptation of The Darling Buds of May

Bartlett, who recently played Siena Rosso in Netflix's period drama Bridgerton, is taking on the role of Mariette Larkin and starring opposite Tok Stephen (Grantchester), who'll portray Cedric 'Charley' Charlton in the upcoming comedy-drama.

The Larkins, which is based on H.E. Bates' novel The Darling Buds of May, is set in the 1950's and follows a working-class family led by "golden-hearted wheeler dealer" Pop Larkin (Walsh) and his wife Ma (The Thick of It's Joanna Scanlan).

Together with their six children, the Larkins navigate their idyllic life in the Kent countryside whilst dealing with threats from government officials and snobbish second home owners.

The series will also focus on the love story between Mariette and village newcomer Cedric 'Charley' Charlton, an unworldly accountant from the city sent to investigate the Larkins' tax affairs who becomes distracted by the beautiful Mariette.

Written by The Durrells screenwriter Simon Nye, the new adaptation aims to capture "the warmth, optimism and escapism of The Larkin family for a modern generation", ITV has teased.

In a statement, Bartlett said she was "really REALLY excited" to be taking on the role of Mariette, adding: "I can't wait to bring these heart-warming stories to life alongside such a wonderful team. It's just the perfect dose of escapism we all need right now."

While Stephen said he was "thrilled" to be cast as Charley. "I can't wait to work alongside Joanna, Bradley and Sabrina. I'm incredibly excited. I hope we can impress fans of the original novels with our version."
