Jon became the fifth evictee
Big Brother contestant Jon Tickle has become the fifth housemate to be evicted from the reality TV show, following Federico Martone out the door on Friday.
The double eviction was introduced after TV bosses decided to spice up the show.
Jon, 29, a data strategy manager, gained more public votes than the third nominee, Cameron Stout, host Davina McCall announced at 2230 BST.
Federico, a 23-year-old Glaswegian waiter, smiled and cheered as his eviction was announced about 90 minutes earlier.
Clearly pleased, Federico let out a loud shriek of "hurray", then told McCall over the house tannoy: "Right, see 'you's' later".
Federico had received 40% of the public's vote.
It was the first time in the current series that the female housemates were guaranteed to stay following the nomination of three men to face the public vote.
Each previous live eviction had seen a female housemate evicted - Justine Sellman, Anoushka Golebiewski and Sissy Rooney - leaving just three in the house alongside six men.
Jon believes Channel 4 decided on the double eviction because the housemates were "too boring" for viewers and there are predictions a new contestant will be introduced.
Federico had been the bookmakers' favourite to leave with odds of 2/9, followed by Cameron at 7/2.
Cameron has not been nominated before
This week the housemates have successfully completed their first group task, giving them more than £150 to spend on food or drink.
Meanwhile, Jon has been criticising Big Brother at length, complaining about the layout of the house and the noise made by the production crew behind the scenes, calling them a "herd of elephants".
Jon has also entered into a war of words with Nush Nowak, he calling her "deceitful and brazen" while she dubbed him an "absolute piffling fool" during an argument.
