Lisa Huo became the fifth housemate to be evicted from the Big brother house after she was voted out ahead of Nikki Grahame, Imogen Thomas and Mikey Dalton in a four-way tussle.

As soon as Grace was given the boot last week, Lisa was odds-on favourite at 4/5 to be next person out of the door with the bookmakers expecting nominations from Aisleyne, Richard, Susie and Pete for the foul mouthed unemployed upholsterer from Manchester.

Big Brother introduced a twist this week for nomination-discussing rule breakers Glyn, Imogen, Lea, Lisa and Nikki who were not be allowed to nominate in the normal fashion. Instead, they each had to nominate one member of their group, on the spot, in front of everyone else. They were not allowed to discuss their choices or nominate themselves and the housemate with the most nominations would automatically face eviction via the public vote. The voting went as follows:

Glyn and Lisa nominated Nikki, Imogen voted for Lea who returned the favour and Nikki voted for Lisa. With two nominations Nikki faced eviction for the third successive week.

The rest of the housemates Aisleyne, Mikey, Pete, Richard and Susie were allowed to nominate as usual in the privacy of the Diary Room. As Nikki was already put up for the public vote, the remaining housemates were not allowed to nominate her, which saw Imogen, Lisa and Mikey thrown into the eviction mix.

By Monday night, Lisa was 1/4 favourite for eviction, despite the remainder of the nominated housemates not being revealed officially until Tuesday evening.

Lisas price shortened considerably as the days neared Fridays eviction night until she was trading at 1/100 so it was no surprise when host Davina McCall announced she was evicted.

Lisa appeared to be expecting to leave as she reacted well with a typical mix of smiles and good natured profanity, hugging each of her housemates in turn and repeating select phrases including sorted mate, mint, take it easy and have fun.

Following a few weeks where housemates have received landslide eviction percentages Grace polling 87.9% and of course Sezers 91.6%, Lisa received a more respectable 60.3% of the vote considering she wasnt trading at odds-against once during eviction week.

Big Brothers latest twist will see five new contestants entering a secret second house next Friday. The new house, accessible via the diary room, features its own bedroom, kitchen, lounge, bathroom and garden area.

Instead of voting to evict a housemate next week, the public will instead choose one housemate to save but live with the five newcomers in the new house.
