The highly anticipated last instalment will return to screens later this month to conclude Poldark's journey. 

The trailer shows Ross Poldark return to Westminster to challenge the king in an attempt to save his friend, while Cornwall appears to descend into chaos. Elsewhere, George Warleggan is still grieving the loss of his wife Elizabeth and, after escaping her abusive husband and finally marrying her love Drake Carne, there's trouble ahead for Morwenna as the teaser shows her distraught as she holds onto her stomach.

Based on the seventh and eighth novels in Winston Grahams' historical series of the same name, the eight-part series will see the return of Aidan Turner (Ross Poldark), Eleanor Tomlinson (Demeleza Poldark), Jack Farthing (George Warleggan​), Elise Chappell (Morwenna), Vincent Regan (Ned Despard) and Harry Richardson (Drake Carne).

The cast will also be joined by some new faces, including Kerri McLean as Kitty Despard, Freddie Wise as Geoffrey-Charles Poldark, the orphaned son of Francis and Elizabeth who decides to follow Ross and enter into the military, and Lily Dodsworth-Evans as Cecilia Hanson, the daughter of slave owner Ralph Hanson who catches the eye of Geofffrey-Charles.

While there are still questions of how the historical drama will end, it's certain there will be many pensive looks across the Cornish cliffs. 

The series will air 14th July at 9pm on BBC One.
