Big Brother contestants Mario Marconi and Rebecca Shiner face eviction on Friday after housemates nominated the pair to face the public vote.

Mario, 43, who has been nominated before, clocked up five votes, with bookmaker’s favourite Kathreya Kasisopa blaming his aggresion: “He's changed so much, I feel very uncomfortable with Mario … he turned very aggressive. Last week he shouted at me and turned the whole house against me… It almost broke my heart," she said as she nominated the bodybuilder.

After a series of tantrums, one in which she smashed a mirror, nursery nurse Rebecca, 21, received four votes from housemates, with Darnell Swallow remarking: “She is fun to a point, but lately the things she's been doing and saying have been straight out of order.”

Mario’s popularity has peaked and troughed during his time on the Channel 4 reality show. He faced nomination once before and then languished at the bottom of bookmaker’s favourite tables for several weeks before finding respite when viewers turned against Sylvia Barrie and Jennifer Clark, who they later evicted.

Rebecca, known as Bex, was a low-profile contestant until several female housemates were evicted and she revealed a loud and frequently angry persona.

Despite the arrival of three new housemates last Friday, Kathreya remains the favourite to win, while Rebecca is now the least likely candidate to pick up the £100,000 prize.
