MAFS UK'S most explosive episode to air tonight as couple cracks and wife walks

Tuesday night's episode of Married at First Sight UK is set to dial up the drama following Monday's commitment ceremony with cracks beginning to show between one of the strongest couples

Married at First Sight UK fans will barely have a chance to catch their breath as tonight's episode (October 22) is set to dial up the drama even further following Monday's explosive commitment ceremony.

Last night, viewers saw tensions rise as Hannah and Stephen called time on their tumultuous marriage. Meanwhile, Richelle revealed her husband Orson's relationship with Hannah had been blossoming secretly, prompting Lacey to announce to the group that she knew the pair had kissed.

Lacey's revelation didn't go down well with Alex who called her a 'snake' for getting involved. He also took aim at Richelle for claiming he and partner Holly had gone on an off-screen double date with Hannah and Orson.

The situation only intensified when Sacha, irritated by Alex's tone, accused him of speaking down to the women in the group. The events sparked further tensions between Sacha and husband Ross after she confronted him about failing to back her up in the tense exchange with Alex, insisting "my drama is your drama."

Ross's insistence that he "won't get involved in drama" ultimately spells the beginning of the end for the marriage. In a preview for tonight's episode, tensions only appear to escalate between the pair.

"I am not comfortable with you being in this apartment," Sacha is seen telling Ross. "I am going to struggle to recover from this. F***** up my head." Ross then stands up and says "I'm going".

Recounting to OK! how their relationship unravels, Sacha said: "I actually end up piping up at some point, somebody puts 20p in me, and all of a sudden I end up having a disagreement with one of the other male cast members.

"It does end up getting between me and Ross and causing a little bit of friction between us, because he is friends with one of them, and it all goes t*ts up from there.”

Ross recently went public with a new girlfriend, confirming to MAFS UK fans that he and Sacha didn't make it outside of the experiment. While they do make it to the final vows in the show, and reportedly even moved in together briefly, their relationship ended shortly after filming wrapped.

Tonight's episode is Love/Hate week, with all of the couples getting brutally honest about what they like, and don't, about their partners. There is also a shock revelation from Holly, who confesses to a crying Lacey that she's "going home", telling the cameras "get me out of here."

MAFS UK continues tonight at 9pm on E4
