Ross Poldark will face new threats in the fourth series of BBC One\'s

: a renowned duellist, a rival for Demelza\'s heart and hot-tempered politicians in Westminster.

The rakish, pistol-happy socialite Monk Adderley is a new addition to the series – played by Max Bennett, he\'s an ally of George Warleggan (Jack Farthing) who Bennett describes as "the dark reflection" of Ross.

"They\'re described in the novel as wild men, so they\'re kindred spirits in that sense," the actor told press including Digital Spy.

"You can see them as two sides of the same coin. He\'s the dark reflection of Poldark. I think they both recognise that in each other, and there\'s sort of an innate animosity between them."

series 5 "might be the last one" – but the show could "come back in 10 years"

While Monk leeches off of George "to fund his lavish lifestyle", George in turn takes advantage of his new ally\'s considerable influence and "powerful friends" in London, forming a devilish double-act for Ross (Aidan Turner) to contend with.

"George is quite vicious in this series," Turner explained. "When he\'s in Westminster, that seems to be the centre of the rat\'s nest for him, to some degree. So he\'s in his comfort zone."

With George now pursuing a career in politics, Ross decides to do likewise in the new

episodes, aiming to take down his nemesis from within the belly of the beast. "Ross needs to take the fight to Westminster," said Turner. "I think he\'s good at being a leader and fighting for a just cause.

"But it\'s a bit of a madhouse. It\'s hard to be heard, [and] it\'s hard to hear other people. It\'s dog-eat-dog."

Ross\'s rivalry with Monk will hit closer to home, too, as the troublemaker decides to turn his attentions to Demelza (Eleanor Tomlinson). "She\'s a fish out of water in London society, so that\'s a lot of fun for him," Bennett revealed. "Obviously she\'s beautiful, so he\'s attracted to her... and his flirtation with her is a way of getting at Ross as well."

Monk, though, might have a tough job getting in-between Cornwall\'s no. 1 power couple. Demelza might have strayed with the charming Hugh Armitage (Josh Whitehouse), but there\'s "a revival" in her marriage to Ross this series.

"It\'s them taking their relationship on and recovering from the pain they have caused each other and rebuilding their lives together," Tomlinson explained. "That\'s where we find them, trying to pick up the pieces."

\'s Eleanor Tomlinson reveals what we can expect from Demelza in series 4

"It\'s a difficult time when we start the series," acknowledged Turner. "He\'s pretty gutted that she\'s fallen in love with somebody else, and has had more than just a fling with this character Hugh.

"It\'s hard for him, because there\'s a serious double standard there if he has any problem with that, I suppose. Relationships are complex... It\'s just about honesty and speaking plainly. Listening is vital... and that\'s something Ross isn\'t necessarily very good at, at the best of times!

"But I think it\'s a new lease of life for them, for both. There\'s some sort of revival in the relationship, which is fun... because actually the last couple of years have been a bit rough!"
