Jonny and Sophie face Brother vote

Jonny Regan has been nominated before

Jonny Regan and Sophie Pritchard are the latest housemates to be nominated for eviction from Channel 4's reality TV show Big Brother.

It is Jonny's second nomination in the last three weeks, with the County Durham firefighter staying in the show ahead of Lee Davey last time.

There has been speculation that Sophie would be nominated, as she did not seem to get on with some of the other contestants who are all vying for the £70,000 prize.

Alex Sibley is the hot favourite to win

The public will vote to decide who will be evicted on Friday, using either phone, text message or interactive television.

Channel 4 said ratings for the show were rising, with the average audience for the series' fourth week reaching 5.1 million.

This is increase of 17% compared with the same period last year, which attracted 4.3 million viewers.

Contestants in the show are filmed 24 hours a day as they choose who to nominate for eviction each week. The public then has the final say, having watched the housemates in action on TV.

Friday's 2200 BST eviction show attracted 5.8 million viewers, with Saturday's episode, showing the housemates performing a task live, pulling in 4.5 million viewers.

Jade has repeatedly discussed nominations

Last week's vote saw Spencer Smith, an early favourite, evicted ahead of male model Alex Sibley, the current tip to scoop the prize.

Jonny, 29, received four votes and Sophie gained three from fellow housemates, delivered in secret in the show's Diary Room.

Sophie, 25, a recruitment consultant from Marlow, Buckinghamshire, entered the house as a replacement for trainee barrister Sunita Sharma, who walked out.

Viewers watched her spending much of her time with Lee, before getting into disagreements with other housemates after his departure.

Jade Goody decided to nominate Sophie as she found her "very false" and thinks she "creeps around people".

PJ Ellis said he nicknamed her "Miss Knowledge" for the way she "butts into conversations", while newboy Tim Culley said she was the only girl he found irritating.
