Poldark is returning to BBC One for another season of post-Revolutionary War drama. 

The season ended with two shocking betrayals that could change the relationship between Ross Poldark (Aidan Turner) and wife Demelza (Elanor Tomlinson). During the final episode, the Captain’s wife locked lips with Hugh Armitage (Josh Whitehouse) before learning that she wasn’t the only one with loose lips. 

Her husband, she learned, had kissed Elizabeth (Heida Reed) in church.

Poldark Season 4 spoilers 

According to Poldark script writer Debbie Horsfield, the fourth season of the BBC One show will be inspired by parts of Winston Graham’s sixth book in the seven-book Poldark anthology. 

She told Radio Times viewers can expect to see Ross Poldark head for Westminster in the new season to claim rival George Warleggan’s Parliament seat.

‘He does take George’s seat. He beats George. At the end of this series we see him coming to the realisation that next time a seat is offerent he has to take it.

‘He’s not desperate to head off to Westminster but a catastrophic happening in episode one of series four makes him realize that in order to have the power to effect any change he needs to get out of his comfort zone.’

Poldark viewers will also get to experience London a bit. 

Horsfield said: ‘That’s a thing we haven’t really seen. We saw it when Caroline [Gabriella Wilde] was in London. There are whole sequences where we go to London and that’s a really exciting new flavor to it.

‘We will meet real characters, like [Prime Minister] William Pitt and [anti-slavery campaigner] William Wilberforce. There are some wonderful affirming storylines and some utterly tragic ones coming up. 

She added that Ross and Demelza will have to ‘work through this sticky patch’ in season four. 

‘What we explore in the fourth series, essentially, is her reasons for this little excursion, shall we say, are many and complex,’ she said.

‘I have often thought in a way it was the perfect storm of Hugh being an opportunist, playing on her sympathies, Ross being occupied elsewhere, Demelza sort of in a way enjoying being wood and courted in a way which she hadn’t been in the early stages by Ross because she obviously went from being his servant to his wife.’
